Obesity-associated type 2 diabetes is now recognized as a state of chronic, low-grade metabolic inflammation, or metaflammation, driven by adipose tissue immune activation, ectopic lipid deposition, gut dysbiosis, and oxidative stress. This inflammatory tone often precedes overt hyperglycemia and structural complications, suggesting that early detection of metaflammation could refine risk stratification and enable preventive intervention. However, current clinical markers such as fasting glucose, HbA1c and standard lipid panels are relatively insensitive to early inflammatory shifts and provide limited spatial or temporal resolution. Emerging nanodiagnostic technologies leverage the unique optical, electrical, magnetic and catalytic properties of nanomaterials to detect inflammatory biomarkers at ultra-low concentrations in small, minimally invasive samples. Metal, carbon, polymeric and hybrid nanostructures can be integrated into biosensors, imaging probes and wearable devices to quantify cytokines, adipokines, acute-phase proteins, microRNAs, exosomes and oxidative stress products associated with metaflammation in obesity and diabetes. These platforms offer high sensitivity, multiplexing capacity and potential for real-time monitoring in blood, interstitial fluid, saliva, sweat and breath. This review outlines the biological basis of metaflammation in obesity-associated diabetes, the evolving biomarker landscape, and the main classes of nanodiagnostic platforms. It highlights preclinical and early translational evidence, discusses technical and regulatory challenges including specificity, standardization and nanotoxicology, and explores future directions such as point-of-care multiplex panels, integrated wearables and AI-assisted interpretation. By enabling earlier and more precise detection of metaflammation,
nanodiagnostics may support personalized prevention and more efficient management of obesity-associated diabetes.
