Gastroesophageal reflux disease (GERD) is a highly prevalent condition. Screening for
GERD remains a great challenge due to the non-specific nature of the symptoms. Now …

Squaraine dyes have excellent photostability with intensive absorption and strong
fluorescence in the near-infrared (NIR) region. However, they display a strong tendency to …

Neutrophil elastase (NE), a serine proteinase, is a significant biomarker which is closely
related to the progress of diseases. However, only few probes have been reported for …

Chymotrypsin, a crucial enzyme in human digestion, catalyzes the breakdown of milk
