Shreya graduated with a BSc from UKZN majoring in microbiology and biochemistry and then went on to complete her BSc honours in microbiology. Due to her interest in the cosmetic industry, she is currently pursuing an MSc in biochemistry with a focus on nanotechnology.
ABSTRACT Nanoparticles (NPs) are increasingly utilized in cosmetic applications due to their unique physicochemical properties, including enhanced UV absorption, ingredient stability, and biocompatibility (Raszewska-Famielec & Flieger, 2022). These properties facilitate their incorporation into sunscreens, lotions and creams, therefore, offering improved skin protection and aesthetic benefits. NPs are currently in use in commercially available products as UV filters (Chakraborty et al., 2024 and Mascarenhas-Melo et al., 2023). Silver NPs have shown to exhibit antimicrobial properties which allow for their incorporation into acne-focused products (Raj et al., 2012). However, concerns regarding the potential toxicity and environmental impact of conventionally synthesized NPs necessitate a shift towards greener synthesis strategies. Traditional methods often involve hazardous chemicals, raising concerns about human and environmental safety. This study employs green synthesis, utilizing natural reducing agents from plant extracts hence offering a more environmentally friendly alternative. The tuberous root extract of the African Wild Ginger produced silver (Ag) NPs with a mean size of 12 nm and mostly spherical in shape with good stability and dispersity. These were then tested for antimicrobial and antioxidant activities and preliminary results confirm the strong antibacterial and antioxidant potential of the silver NPs which indicate promising activity. |
