Glucose-responsive drug delivery systems aim to emulate pancreatic feedback by sensing hyperglycemia and releasing therapeutics proportionally, thereby improving time in range while mitigating hypoglycemia. In people with diabetes and coexisting obesity, the value proposition is amplified by altered pharmacokinetics in expanded adipose depots, variable subcutaneous perfusion, chronic low-grade inflammation, and behavioral burdens associated with frequent injections and complex dosing. Smart nanomaterials like lipid, polymer, hydrogel, and hybrid architectures endowed with enzymatic, chemical, or physical glucose-sensing motifs offer the spatial and temporal control required for adaptive delivery of insulin and adjunct agents. This review synthesizes design principles for responsive nano platforms; compares enzymatic (glucose oxidase/dehydrogenase), boronic acid–diol, and lectin strategies; examines device-route integration via microneedles, subcutaneous depots, oral and pulmonary formulations; and discusses peroxide management, antifouling strategies, and closed-loop–like kinetics. We evaluate safety, manufacturability, and regulatory pathways tailored to chronic metabolic indications and obesity-related physiology, and propose clinical trial frameworks that pair continuous glucose monitoring with imaging and mechanistic biomarkers. Finally, we highlight human factors such as usability, adherence, equity, and compatibility with incretins and SGLT2 inhibitors that will determine real-world impact. Smart nanomaterials can decouple efficacy from risk by matching dose to demand, offering patient-centered control that complements contemporary pharmacotherapy.
