TL;DR: The practicality and viability of this fluorescent probe were demonstrated through the analysis of silver ion in real river water and human serum samples and the prepared S,N-CQDs possessed low cytotoxicity and good biocompatibility.

TL;DR: A novel strategy of simultaneous in situ extraction and fabrication of surface-enhanced Raman scattering substrate (IE-SERS) to perform selective and reliable on-site determination of thiram residue in soil, fruits, and vegetables, indicating that the established method has great potential in the in situ ultrasensitive detection ofThiram on irregular fruits and vegetables.

TL;DR: This aptasensor exhibits a high sensitivity toward AFB1 with a detection limit of 0.02 ng/mL and shows higher selectivity for AFB1 compared to other reported agents and can be employed to detect AFB1 in foodstuffs, which might find broad practical applications in other food contaminants determination.

TL;DR: A novel colorimetric sensor for in-field detection of antibiotics by using aptamer (Apt)-capped and horseradish peroxidise (HRP)-embedded zeolitic metal azolate framework-7 (MAF-7) ( a new design pattern for developing on-site antibiotics assays and immensely extends the application of enzyme embedded metal-organic framework composites.

TL;DR: A novel facile method for on-site determination of sulphite in wine using a gas-diffusion microfluidic paper-based analytical device (μPAD) combined with surface-enhanced Raman spectroscopy (SERS) was explored and can be essentially paralleled with the official method.
