“…NMNPs such as Ag, Au, Pd, and Pt have been highlighted to have several applications in material science, chemistry, and medicine [ 5 , 6 , 7 ]. Platinum nanoparticles (PtNPs) have received much more attention among researchers due to their distinctive structural, catalytic, and optical properties, as well as their large surface area, which makes them a promising choice for catalytic and biological applications [ 8 , 9 ]. PtNPs have been reported to be a capable and effective drug carrier [ 10 ].…”

Noble metal nanoparticles (NMNPs) are viable alternative green sources compared to the chemical available methods in several approach like Food, medical, biotechnology, and textile industries. The biological synthesis of platinum nanoparticles (PtNPs), as a strong photocatalytic agent, has proved as more effective and safer method. In this study, PtNPs were synthesized at four different temperatures (25 °C, 50 °C, 70 °C, and 100 °C). PtNPs synthesized at 100 °C were smaller and exhibited spherical morphology with a high degree of dispersion. A series of physicochemical characterizations were applied to investigate the synthesis, particle size, crystalline nature, and surface morphology of PtNPs. The biosynthesized PtNPs were tested for the photodegradation of methylene blue (MB) under visible light irradiations. The results showed that PtNPs exhibited remarkable photocatalytic activity by degrading 98% of MB only in 40 min. The acid phosphatase mediated PtNPs showed strong bacterial inhibition efficiency against S. aureus and E. coli. Furthermore, it showed high antioxidant activity (88%) against 1,1-diphenyl-2-picryl-hydrazil (DPPH). In conclusion, this study provided an overview of the applications of PtNPs in food chemistry, biotechnology, and textile industries for the deterioration of the natural and synthetic dyes and its potential application in the suppression of pathogenic microbes of the biological systems. Thus, it could be used as a novel approach in the food microbiology, biomedical and environmental applications.

“…Moreover, the green source-derived polysaccharide has been used for the preparation of highly stable platinum nanoclusters, which showed high selectivity and sensitivity for the detection of glucose and glutathione in biological fluids ( Dong et al., 2021 ; Fan et al., 2021 ). Thus, it can be assumed that phytochemicals reduced metallic nanoclusters/phytofabricated metallic nanoparticles would show high selectivity for the cellular transportation and utilization of glucose.…”

The integration of nanotechnology with herbal medicines overcomes the limitations of herbal therapy and offers desirable bioactivity. Thus, this study was aimed at synthesizing Apium graveolens -gold nanoparticles (AG-AuNPs) and exploring their impact on the glucose utilization pattern of the isolated rat hemidiaphragm. The AG-AuNPs appeared in cherry red color and showed a plasmonic peak at 534nm. The bio-reduced AG-AuNPs appeared as spherical shapes with varying sizes of about 4–15 nm. It also depicted the zeta potential of -19.5 mV, face-centered cubic crystalline nature, stretching vibrations for different functionalities, and in vitro stability during various characterization studies. The AG-AuNPs showed non-cytotoxicity and promoted cellular glucose uptake on their exposure to the cell line and the diaphragm, respectively. Moreover, the identified flavonoids and polyphenols of AG depicted in silico interactions with the insulin signaling molecule. The observed results suggest that the interacting ability of AG-AuNPs with the insulin signaling molecule can promote the glucose uptake efficiency of the diaphragm.

“…A variety of substances with peroxidase-like properties sprung up like mushrooms, from noble metal nanoparticles [ 6 ], metal oxides [ 7 ], to multi-metal compounds [ 8 ]. This peroxidase-like activity of nanozymes has been used in colorimetry to detect many biologically related substances, such as H 2 O 2 [ 9 ], glucose [ 10 ], DA [ 11 ], and glutathione [ 12 ]. While great progress has been made, there are still some difficulties and challenges in the study of nanozymes.…”

The sensitive and selective detection of dopamine (DA) is very important for the early diagnosis of DA-related diseases. In this study, we reported the colorimetric detection of DA using Ganoderma lucidum polysaccharide (GLP) stabilized platinum nanoclusters (Ptn-GLP NCs). When Pt600-GLP NCs was added, 3,3’,5,5’-tetramethylbenzidine (TMB) was rapidly catalyzed and oxidized to blue oxTMB, indicating the peroxidase-like activity of Pt600-GLP NCs. The catalytic reaction on the substrate TMB followed the Michaelis-Menton kinetics with the ping-pong mechanism. The mechanism of the colorimetric reaction was mainly due to the formation of hydroxyl radical (•OH). Furthermore, the catalytic reaction of Pt600-GLP NCs was used in the colorimetric detection of DA. The linear range for DA was 1–100 μM and the detection limit was 0.66 μM. The sensitive detection of DA using Pt-GLP NCs with peroxidase-like activity offers a simple and practical method that may have great potential applications in the biotechnology field.
