Food safety is directly related to human health and has attracted intense attention all over the world. Surface-enhanced Raman scattering (SERS), as a rapid selective technique, been widely applied in monitoring food safety. SERS substrates, an essential factor for sensing design, greatly influence analytical performance. Currently, nanostructure-based substrates have garnered significant interest due their excellent merits improving sensitivity, specificity, stability, holding great potential accurate of contaminants complex matrices. This review summarizes fundamentals spectroscopy used nanostructures designing platform, including precious metal nanoparticles, metal-organic frameworks, polymers, semiconductors. Moreover, it introduces mechanisms applications enhancing signals hazardous substances, such foodborne bacteria, pesticide veterinary drug residues, additives, illegal adulterants, packaging material contamination. Finally, with continuous progress nanostructure technology improvement technology, its application prospect testing will be broader.

To provide individuals with healthier and more reliable dietary recommendations for diabetic patients, a pragmatic electrochemical sensing toward in situ monitoring of glucose saliva was designed noninvasive evaluation high-starch food digestion. The proposed sensor constructed by exploiting carbon-based nanostructure electrical conductivity Ni-based nanozyme direct catalytic oxidation signal output. Particularly, the host-guest interaction between investigated to be hydrogen bond via molecular docking, C11 O5 sites molecule were attacked during reaction through density functional theory (DFT) research. With merits simplicity, sensitivity, accuracy, exhibited good performance detection limit 10 μM (corresponding 1.8 μg mL-1). Moreover, it well qualified point-of-use trace levels saliva, offering promising tool digestion (e.g., Wheat bread, Steamed bun, Shao-mai) at different times after meals eventually yielding benefits patients.
