Nano Express, 2025
The internalization of cerium oxide nanoparticles (CeO2−x NPs) in articular cartilage presents a novel approach to enhance imaging modalities for monitoring osteoarthritis (OA). This study introduces a bimodal cerium oxide-based nano-contrast agent synthesized via a one-step combustion method, aimed at addressing the limitations of earlier synthesis techniques that lacked dual functional properties for bioimaging. The combustion method produces high-yield nanoparticles that exhibit exceptional x-ray attenuation and redox properties, while also enhanced optical characteristics due to quench annealing processes. CeO2−x NPs quench annealed at 700 °C (C7 NPs) were identified as effective bimodal contrast agents for cartilage imaging. Characterization of C7 NPs revealed distinct fluorescence emissions: greenish-blue (λ em = 381 nm) and yellowish-pink (λ em = 406 and 454 nm) under UV-C and UV-A excitation, indicating efficient down-conversion due to their unique size and energy band structures. The x-ray attenuation properties were assessed using tissue-mimicking phantoms, demonstrating values between 502 and 783 HU·ml/mg at low x-ray tube voltages, utilizing a custom-built benchtop micro-CT system. Ex vivo optical imaging conducted on goat articular cartilage tissues confirmed the effective internalization of C7 NPs (∼20 nm) within the transitional zone. This study is the first to report the internalization of combustion-synthesized CeO2−x NPs in goat articular cartilage explants, underscoring their potential as bimodal agents for x-ray and optical imaging in articular cartilage tracking.

Research shows that the implementation of home-based physical therapy (HBPT) is a vital part of many rehabilitation programs. However, non-adherence rates reach up to 70%, which negatively affects the treatment outcomes. Studies suggest that when physical therapy interacts with game-related activities patients are more likely to follow exercise protocols and achieve better rehabilitation outcomes. This research describes a novel web-based platform called PhysioGame which leverages this concept by integrating physical therapy exercises with engaging game elements. The application presents three exercise categories based on physical therapy practices. These are: balance, strengthening, and stretching, which targets specific body parts such as shoulder, elbow, knee, and upper back. Real-time monitoring of user movements occurs through the webcam via Mediapipe Pose library to verify correct exercise performance with proper posture. This helps users achieve better outcomes from their therapy sessions. PhysioGame also includes a gamified reward system where users earn coins based on their performance. The coins earned through gameplay, enables them to purchase various virtual plants and decorate their digital gardens to enhance both motivation and entertainment factor. The stored garden data persists between sessions so users can continue enjoying their decorated environments across different sessions. By combining physical therapy with interactive gaming, PhysioGame aims to make the rehabilitation process more enjoyable, improve user engagement, and ultimately enhance the effectiveness of physical therapy.

This study presents an automated colorimetric detection system that overcomes the limitations of manual biomarker analysis by integrating a TCS34725 RGB sensor with Arduino Nano processing for objective, real-time diagnostics. The portable device captures test strip color changes, processes RGB data through calibrated algorithms, and displays results (<3 seconds) on an OLED screen with 96% accuracy relative to laboratory standards. By eliminating human interpretation errors, the system improves reliability while maintaining cost-effectiveness (<$50) and low power consumption (8–10-hour battery life). Validations demonstrated consistent performance across varying lighting conditions through software-based calibration with brightness normalization and hue correction. The current implementation focuses on pH detection but features expandable architecture for multiplexed biomarker analysis. With applications in point-of-care diagnostics, food safety, and environmental monitoring, this platform enables accessible testing in resource-limited settings. Future development will incorporate machine learning for adaptive calibration, IoT connectivity for cloud-based data logging, and mobile integration to enhance remote diagnostic capabilities, positioning the system as a versatile solution for decentralized testing needs.
Nanobiohybrids: A promising approach for sensing diverse environmental water pollutants
Angelene Hannah Jebarani D., Sruthi Ann Alex
Nanobiohybrids for Advanced Wastewater Treatment and Energy Recovery, 2023
Water resource management has become the need of the hour with continuous depletion of good quality water. Sensors are important tools for monitoring the environmental water quality and quantifying the presence of various harmful pollutants (pesticides, heavy metals, and micro-organisms). Biosensors designed with functional biological molecules as recognition elements use a transducer, which converts a biological response into electrochemical, optical, gravimetric, magnetic, or thermal signals that can be easily quantified. The advent of nanotechnology has revolutionized material design and properties of sensing platforms. Materials in the nanoscale dimension possess interesting characteristic features such as high surface-area-to-volume ratio, high conductivity, functionalizability, shock-bearing ability, color tunability, photo-reactivity, and magnetization. Nanomaterial-integrated biomolecules with enhanced functional properties are termed as nanobiohybrids. The amalgamation of the tuneable characteristics of nanomaterials with functional biological molecules by means of functionalization and/or immobilization creates sophisticated transducers for enhancing the analytical performance of sensors. The resultant nanobiohybrid sensor systems are robust, exhibit relatively short response time with improved specificity and have higher sensitivity enabling detection of even trace volumes of analyte molecules. Recent advancements in research and engineering also promote the possibilities of device miniaturization, portability, and incessant monitoring of water quality. This chapter intends to discuss the impact of various toxic pollutants in water, the importance of nanomaterials in design of novel nanobiohybrids, the different nanomaterials relevant for use in design of sensors for environmental analysis, and finally the different transduction mechanisms that enable the detection and quantification of toxins in water.
Studies on the removal of acid violet 7 dye from aqueous solutions by green ZnO@Fe3O4 chitosan–alginate nanocomposite synthesized using Camellia sinensis extract
Namrata Roy, Sruthi Ann Alex, N. Chandrasekaran, Krishnan Kannabiran, Amitava Mukherjee
Journal of Environmental Management, 2022
In the present study, ZnO-Fe3O4 nanoparticles were synthesized using the leaves of Camellia sinensis and immobilized in crosslinked alginate-chitosan polymer beads and tested for their photocatalytic applications. The prepared nanocomposite was used for the simultaneous adsorption and photocatalytic degradation of acid violet 7 (AV7) dye. The optimization of reaction conditions ensured higher dye removal efficacy up to 94.21 ± 1.02% using the nanocomposite under UV-C irradiation of 365 nm. The kinetics of the adsorption study fitted well with the pseudo-first-order reaction. The Langmuir model fitted better to the adsorption isotherms compared to the Freundlich and Temkin models. The mechanism of degradation was studied by analyzing the treated AV7 solution. The removal efficiency in tap water, groundwater, and lake water was 83.23 ± 0.4%, 69.13 ± 1.6%, and 67.89 ± 0.3%, respectively. The residual toxicity of the degraded AV7 solution was tested on model organisms like freshwater algae, Scenedesmus sp., and plant model, Allium cepa, demonstrating the lower toxicity of the degraded AV7 product. Finally, a cost-benefit analysis of the experiments was also carried out.
Development of biogenic bimetallic Pd/Fe nanoparticle–impregnated aerobic microbial granules with potential for dye removal
Hemamalathi Kubendiran, Sruthi Ann Alex, Mrudula Pulimi, N. Chandrasekaran, Y.V. Nancharaiah, V.P. Venugopalan, Amitava Mukherjee
Journal of Environmental Management, 2021
The objective of this study was to develop bimetallic core-shell Pd/Fe nanoparticles on the surface of aerobic microbial granules (Bio-Pd/Fe) and to evaluate their dye removal potential using a representative dye, methyl orange (MO). The aerobic microbial granules (1.5 ± 0.32 mm) were grown for 70 days in a 3-L glass sequencing batch reactor (SBR) with a 12-h cycle time. The Bio-Pd/Fe formation was catalyzed by the Bio-H2 gas produced by the granules. The developed Bio-Pd/Fe was further used for MO removal from aqueous solutions, and the reaction parameters were optimized by response surface methodology (RSM). The XRD, SEM, EDAX, elemental mapping, and XPS studies confirmed the formation of Bio-Pd/Fe. Under the optimized removal conditions, 99.33% MO could be removed by Bio-Pd/Fe, whereas removal by Bio-Pd, Bio-Fe, aerobic microbial granules, and heat-killed granules were found to be quite low (68.91 ± 0.2%, 76.8 ± 0.3%, 19.8 ± 0.6%, and 6.59 ± 0.2%, respectively). The mechanism of removal was investigated by UV-visible spectroscopy, redox potential analysis, HR-LCMS analyses of the solution phase, and XRD and XPS analyses of the solid sorbent. The degradation products of MO exhibited m/z values corresponding to 292, 212, and 160 m/z. The remnant toxicity of the intermediate degradation products was analysed using freshwater algae, Scenedesmus sp. And Allium cepa, as indicator organisms. These assays suggested that after the treatment with Bio-Pd/Fe, MO was transformed to a lesser toxic form.

Journal of Environmental Chemical Engineering, 2021
Diverse antibiotic drugs have been used for the treatment of bacterial infections; however, their overuse, improper handling, and limitations in treatment facilities can result in their accumulation and biotransformation in the water systems. These bio-accumulated antibiotics can lead to more detrimental effects due to the emergence of multi-resistant bacterial genes at the micro-level, which in turn enhance the chances of bacterial survival. The current review discusses the prevalence of this contaminant in India and different countries around the globe. Since prevention of antibiotic release is the most effective strategy for controlling water pollution, the importance of several governing bodies and their guidelines for antibiotic use and release have been discussed. As a solution to the increasing threat of antibiotics in treated wastewater and natural waters, various treatment strategies have been explored, of which photocatalytic degradation is one of the significant treatment options. In particular, the review focuses on the multiple approaches of photocatalytic degradation in a stand-alone system and in combination with other techniques and nanomaterials. Different photo-active materials, reactor systems, oxide molecular release, kinetic mechanisms, influence of different parameters and characterizations involved have been discussed in detail in order to understand the optimum conditions for photocatalytic degradation of antibiotics.
