Real‐time quality and safety monitoring of fruit juice using paper‐based platform
Food Biomacromolecules, Volume 3, Issue 1, Page 140-162, March 2026.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.

Quorum Sensing of Acidophiles: A Communication System in Microorganisms
, 2021 Communication is important for organisms living in nature. Quorum sensing system (QS) are intercellular communication systems that promote the sociality of microbes. Microorganisms could promote cell-to-cell cooperation and population density to adapt to the changing environment through QS-mediated regulation that is dependent on the secretion and the ...
