Enzymatic Sensors
Traditional methods like Glucose Oxidase (GOx) and Glucose Dehydrogenase (GDH) are known for their high specificity. However, they face challenges with instability, environmental sensitivity, and interference from other biomolecules. Recent advances focus on improving enzyme stability and reducing interference through advanced immobilization techniques and mediator systems.
Non-Enzymatic Sensors
These leverage metals and nanomaterials for direct glucose oxidation, offering higher sensitivity, cost-effectiveness, and stability compared to enzymatic counterparts. Challenges include selectivity in complex biofluids and performance at physiological pH, driving research into novel nanomaterials and hybrid structures.
Non-Invasive Methods
Future-forward techniques utilizing alternative biofluids (saliva, tears, sweat, breath) for glucose detection promise enhanced patient comfort. While offering minimal invasiveness, current limitations include low glucose concentrations in these biofluids and variable correlations with blood glucose levels, necessitating significant sensitivity improvements.

Clinical Adoption Challenges
Patient Compliance & Accessibility in Diabetes Management
A study at Zagazig University Hospital found that low patient compliance with type 2 diabetes treatment was primarily due to income and education levels. Similarly, Chinese guidelines show only 56.7% adequate compliance, with duration of diabetes and oral hypoglycemic agents positively impacting adherence. These findings underscore the need for accessible, affordable, and easily understandable glucose monitoring solutions, particularly for underserved populations, and highlight the importance of patient education to improve treatment adherence and metabolic control.
