Nanoparticle-Based Drug Delivery Systems for Diabetes Management
Summary
Diabetes mellitus remains a leading global health challenge characterised by chronic hyperglycaemia and multiorgan complications. Conventional therapies, including subcutaneous insulin injections and oral hypoglycaemic agents, often suffer from poor patient adherence, fluctuating blood glucose control and systemic side effects. Nanoparticle-based drug delivery systems offer novel solutions by encapsulating antidiabetic agents within carriers typically ranging from 10 to 500 nm in size. These nanocarriers—such as liposomes, polymeric nanoparticles, solid lipid nanoparticles and inorganic nanostructures—can protect labile molecules from enzymatic degradation, enhance mucosal absorption, enable controlled or stimuli-responsive release and allow tissue-specific targeting. Advances in surface functionalisation with ligands or antibodies have further refined delivery to pancreatic β-cells, inflamed vasculature or wound sites. Moreover, glucose-responsive materials and enzyme-mimicking “nanozymes” have emerged to provide on-demand insulin or antioxidant activity, improving glycaemic stability and mitigating oxidative stress. Together, these strategies hold promise for improved therapeutic efficacy, reduced dosing frequency and minimised adverse reactions in diabetes management.

Nanoparticle-Based Drug Delivery Systems for Diabetes Management publication trend
The graph below shows the total number of articles in nanoparticle-based drug delivery systems for diabetes management across all publications each year (not limited to Nature Index journals).
Technical terms
Nanoparticle: A particle with dimensions in the nanometre scale (1–1000 nm), used as a carrier for drugs to improve delivery and efficacy.
Bioavailability: The proportion of an administered drug that reaches systemic circulation intact and is available for therapeutic action.
Oxidative stress: A state in which the production of reactive oxygen species exceeds the body’s antioxidant defence, contributing to tissue damage.
Liposome: A vesicular nanocarrier composed of phospholipid bilayers capable of encapsulating both hydrophilic and hydrophobic drugs.
Polymeric nanoparticle: A solid colloidal particle formed from biocompatible polymers that can encapsulate drugs and release them in a controlled manner.
Nanozyme: A nanomaterial exhibiting enzyme-like catalytic activity, used to modulate biochemical reactions such as reactive oxygen species scavenging.
Stimuli-responsive release: A mechanism by which drug delivery systems alter their release profile in response to environmental triggers (e.g. pH, glucose concentration).
