Real‐time quality and safety monitoring of fruit juice using paper‐based platform

Food Biomacromolecules, EarlyView.
Schematic illustration of a paper‐based biosensor for rapid detection of fruit juice spoilage. Abstract Food spoilage and safety concerns still remain critically challenging within the fruit juice industry, especially as conventional detection methods, though precise, are often too time‐consuming, costly, and reliant on centralized laboratories.

Discrimination of Tryptophan Enantiomers at Sub‐pm Level by Multiparametric Analysis of a Label‐Free Organic Immunosensor

Small Methods, EarlyView.
Multiparametric analysis is a crucial aspect for enhancing the final sensitivity of biosensors based on organic transistors. The traditional approaches to treat the experimental data are not always suitable to extract the correct response. In this work EGOT characteristics are processed to achieve enantiodiscrimination of free Tryptophan enantiomers ...
