Colloid Journal, 2025
Abstract This study presents a rapid and eco-friendly approach to synthesize gold nanoparticles (AuNPs) using waste avocado seed extract (AV) as a reducing and capping agent. Microwave irradiation enables the synthesis of AuNPs within a minute, as evidenced by the solution’s characteristic red color and confirmed by a surface plasmon resonance (SPR) peak at ~530 nm in the UV-visible spectrum. Synthesis parameters, including pH and concentrations of AV and gold chloride, were optimized, revealing that mild alkaline conditions favor AuNP formation, while acidic conditions are detrimental. The AuNPs, characterized by transmission electron microscopy (TEM), exhibited a small size (9.9 ± 3.6 nm) and spherical morphology without aggregation. X-ray diffraction (XRD) confirmed the face-centered cubic (FCC) crystal structure of the AuNPs, and Fourier transform infrared (FTIR) spectroscopy indicated the involvement of functional groups in AV in the reduction and stabilization of the nanoparticles. The AV@AuNPs demonstrated excellent stability, as indicated by a high negative zeta potential (–27.0 ± 6.4 mV). Additionally, the nanoparticles showed strong antioxidant activity comparable to ascorbic acid and significant antibacterial efficacy against both Gram-positive (S. aureus and B. subtilis) and Gram-negative (E. coli and P. aeruginosa) bacteria, with a pronounced effect on Gram-negative strains.

Effluents containing dyes, discharged by various industries, have become a significant contributor to water pollution. This study explores the use of green-synthesized palladium nanoparticle (PdNP) catalysts, which offer enhanced catalytic performance compared to traditional methods. The research focuses on the synthesis of palladium nanoparticles using Salmalia Malabarica (SM) gum via a microwave-assisted process and investigates their catalytic and antibacterial properties. SEM analysis confirms the even distribution of PdNPs on the surface of SM gum. Furthermore, TEM analysis reveals a PdNPs size distribution of 10 ± 2 nm. XPS study was used to identify the chemical state of Pd in the synthesized nanoparticles. The results demonstrate that PdNPs are highly effective catalysts for the degradation of dyes such as Methylene Orange (MO), Rhodamine-B (Rh-B), and 4-Nitrophenol (4-NP), even after being reused five times. The catalytic activity of PdNPs was remarkable, achieved 99% dye degradation in four minutes. The degradation data of PdNPs on 4 -NP, MO and Rh-B dyes are followed by pseudo-first-order kinetics with 0.0087, 0.0152 and 0.0164 s− 1, respectively. Additionally, PdNPs exhibit exceptional antimicrobial activity against both bacterial and fungal strains. This synthesis process proves to be cost-effective, devoid of toxic chemicals, and remarkably rapid. The findings suggest promising applications for PdNPs in fields like nanomedicine and environmental remediation, reflecting their potential for addressing water pollution issues.

Platycladus Orientalis mediated green synthesis of crystalline palladium nanoparticles as a potential and promising nano catalyst in the degradation of dyes for mitigation of environmental pollution
Aruna Kumari K, Bhagavanth Reddy G, Ramadevi V, Vasantha Mittepalli
Inorganic and Nano Metal Chemistry, 2025
In the current study, PdNPs were synthesized in a greener way using Platycladus orientalis leaves extract (PO) as a reducing agent with stabilizing ability. UV–Vis Spectroscopy (UV–Vis), Fourier Transform Infrared Spectroscopy (FTIR), X-Ray Diffraction (XRD), Transmission Electronic Microscopy (TEM) and Dynamic Light Scattering (DLS) were implicated in the characterization of nanoparticles. The structural and the morphological studies were determined using TEM and XRD analysis while UV–Vis and FTIR studies further confirmed the presence of optical, physical and chemical properties. The images of TEM manifested spherical NPs with an average size of 8 ± 3 nm. Phytochemicals present in the leaf extract enabled the reduction of Pd+2 to Pd0 and also acted as a stabilizing agent. Later, the catalytic property of PdNPs, reduction of dyes like Rhodamine B (RhB), Methyl Orange (MO) and Crystal Violet (CV) was investigated. This green preparation method of making small spherical shaped PdNPs were successfully applied for the reduction of organic dyes.

For the first time, Frankincense resin (FR) has been carboxymethylated to produce CMFR – AuNPs and the conjugate was utilized for the Doxorubicin drug loading. The carboxymethylation of the carboxylic, phenolic, and hydroxyl functional groups of FR has been developed into carboxymethylated Frankincense resin (CMFR). A novel CMFR-AuNPs was synthesized using the developed CMFR as a stabilizing and reducing agent. The antibacterial, antioxidant, and in-vitro anticancer activities were investigated by using CMFR-AuNPs and CMFR – AuNPs@DOX. CMFR-AuNPs demonstrated antioxidative properties by quenching DPPH radicals effectively. CMFR-AuNPs and DOX@CMFR-AuNPs demonstrated strong antibacterial activity against K. pneumoniae , S. aureus, B. subtilis , and E. coli. The cell viability was tested for CMFR -AuNPs at various concentrations of Dox-loaded CMFR -AuNPs (CMFR-AuNPs + Dox1, CMFR-AuNPs + Dox 2, & CMFR-AuNPs + Dox 3). The highest inhibition was observed on MCF-7 and HeLa cell lines using CMFR-AuNPs + Dox 3, respectively. Various techniques such as UV, FTIR, TGA, XRD, SEM, EDAX and TEM were used to characterize the designed CMFR and CMFR-AuNPs. After carboxy methylation, the amorphous nature of FR changed to crystallinity, as reflected in the XRD spectra. The XRD spectrum of the CMFR- AuNPs showed FCC structure due to the involvement of hydroxyl and carboxylic functional groups of CMFR strongly bound with the AuNPs. TGA results revealed that the CMFR is thermally more stable than FR. TEM revealed that CMFR - AuNPs were well dispersed, spherical, and hexagonal with an average diameter of 7 to 10 nm, while the size of doxorubicin loaded (DOX@CMFR-AuNPs) AuNPs was 11 to 13 nm. Green CMFR-AuNPs have the potential to enhance the drug loading and anticancer efficacy of drugs. • Modifying Frankincense Resin into carboxymethylated Frankincense Resin (CMFR). • TEM revealed that synthesized CMFR - AuNPs were hexagonal and 7–10 nm in size. • DOX@CMFR-AuNPs and CMFR-AuNPs showed excellent antimicrobial activities. • CMFR-AuNPs+Dox3 inhibited MCF-7 and HeLa cell proliferation. • This study can improve the anticancer drug efficacy and reduce adverse effects. • This study could lead to the development of targeted drug delivery systems.
