Green Synthesis of Antidiabetic Nanoparticles

Green synthesis harnesses biological resources such as plant extracts, microbial cultures and agricultural waste to produce metal and metal-oxide nanoparticles under mild, eco-friendly conditions. In antidiabetic research these nanoparticles—commonly based on silver, gold, zinc oxide and graphene composites—exhibit multiple mechanisms of action including inhibition of carbohydrate-digesting enzymes, antioxidant activity, modulation of insulin secretion and improvement of insulin sensitivity. The approach offers cost-effective, low-toxicity routes to nanoscale materials with controllable size, shape and surface chemistry, enabling enhanced bioavailability and targeted delivery. Global efforts have demonstrated efficacy in cell culture and animal models, with reports of reduced postprandial blood glucose, suppression of oxidative stress and restoration of pancreatic β-cell function. Integration of green-synthesised nanoparticles into dietary supplements, topical formulations and drug carriers holds promise for innovative, sustainable therapies. Ongoing challenges include scale-up, reproducibility and comprehensive assessment of long-term safety.

The graph below shows the total number of articles in green synthesis of antidiabetic nanoparticles across all publications each year (not limited to Nature Index journals).

Technical terms

Green synthesis: Production of nanoparticles using biological agents under mild, non-toxic conditions to minimise environmental impact.

Alpha-amylase and alpha-glucosidase: Digestive enzymes that break down starch and sugars; inhibition reduces postprandial blood glucose spikes.

Reduced graphene oxide (RGO): Chemically derived graphene with residual oxygen groups, used as a support matrix to stabilise nanoparticles and enhance electron transfer.

Biocompatibility: The characteristic of a material to interact with living tissues without causing toxicity or adverse immune responses.

Streptozotocin-induced diabetic model: An experimental protocol in which streptozotocin is used to destroy pancreatic β-cells in animals, simulating human diabetes for therapeutic testing.
