“…Contrary to other studies, smaller nanoparticles were observed as the crystallization time increased. This interesting result may be due to rapid nucleation of shorter glucose units and rapid growth in an aqueous solution (Geng et al, 2012). Potato SNPs have a spherical shape of 15-30 nm (Fig.…”

Enzymatic hydrolysis and self-assembly are considered promising methods for preparation of starch nanoparticles (SNPs) because they are environmentally friendly, and time- and cost-effective. These methods are based on the self-assembly of short-chain glucans released from the α-1,6 bonds in amylopectin. Since their discovery, many studies have described the structural and physicochemical properties of self-assembled SNPs. Self-assembled SNPs can be prepared by two methods: using only the soluble portion containing the short-chain glucans, or using the whole hydrolyzate including both insoluble and soluble fractions. Although the structural and physical properties of self-assembled SNPs can be attributed to the composition of the hydrolyzates that participate in self-assembly, this aspect has not yet been discussed. This review focuses on SNPs self-assembled with only soluble short-chain glucans and addresses their characteristics, including formation mechanisms as well as structural and physicochemical properties, compared with SNPs prepared with total hydrolyzates.

“…SUN ShiGang and coworkers [9] investigate the interactions of citrates with the platinum single crystal (100) plane in acid media by using cyclic voltammetry, and reveale that citrates could stabilize the surface domains of the two-dimensional long range order of Pt(100) surfaces. JIANG LiPing and coworkers [10] demonstrate the effects of ultrasonics on crystallization. Ultrasonic-assisted Ostwald ripening and oriented attachment processes are reviewed for possible crystal growth mechanisms for use in the fabrication of inorganic nanostructures [10].…”

“…[16][17][18] Typically metals such as copper, gold, palladium, platinum, and silver from the coinage family are used to synthesize NPs. NPs synthesis can be achieved using different chemical, 19 physical, 20 and electrochemical 21 methods. Considering the harmful effects that these methods could cause on the environment and humans, 22,23 researchers have focused on non-toxic, environmentally benign green chemical routes for the synthesis of metal NPs.…”

Background: Green synthesis of gold nanoparticles (AuNPs) using medicinal plant extract is an emerging area of research due to their applicability in nanomedicines. Methods: In this study, aqueous extracts prepared from fruit-pericarps of two Garcinia species, G. indica (GI) and G. cambogia (GC) fruits which are important medicinally and commercially have been utilized for the synthesis of AuNPs. Various analytical techniques were utilized to characterize the synthesized AuNPs. The synthesized AuNPs were investigated for their biological properties such as antioxidant activity using the (2,2-diphenyl-1-picrylhydrazyl) DPPH model, cytotoxicity against MCF-7 (breast) cancer cell line, and antibacterial activity against two bacterial strains viz. B. subtilis and E. coli. Results: The absorption peak of the AuNPs is observed at 541 nm using UV–Visible spectroscopy. The high resolution – scanning electron microscopy images showed spherical with a triangular shape AuNPs and their average sizes were ranging from 2 – 10 nm and it was found to be in good agreement with the particle size of 8 – 11 nm determined using X-ray diffraction analysis. Fourier-transform infrared spectroscopy revealed that water-soluble biomolecules from the aqueous extracts of the Garcinia species played a crucial role in the formation of AuNPs. The synthesized AuNPs exhibited considerable cytotoxicity with IC50 values 34.55 µg/ml (GI) and 35.69 µg/ml (GC) against the MCF-7 cancer cell line. Furthermore, synthesized AuNPs also demonstrated significant antioxidant and antibacterial properties comparable to the standards used. Conclusion: AuNPs have been synthesized using a simple green approach. The synthesized AuNPs demonstrated promising cytotoxicity, antioxidant, and antibacterial properties.
