Wearable sensors have broad application potential in motion assessment, health monitoring, and medical diagnosis. However, relying on a specialized instrument for power supply and signal reading makes sensors unsuitable for on-site detection. To solve this problem, a reusable self-powered electrochromic sensor patch based on enzymatic biofuel cells were constructed to realize the on-site visualized monitoring.

To ensure high quality of food and water, the identification of traces of pathogens is mandatory. Rapid nucleic acid-based tests shorten traditional detection times while maintaining low detection limits. Challenging is the loss of nucleic acids during necessary purification processes, since elution off solid surfaces is not efficient.

Purpose: Anal fissure (AF) is a common anorectal condition causing pain, bleeding, and other perianal discomfort. This study conducts a network meta-analysis to compare the efficacy and side effect profiles of pharmacological treatments for AF, including diltiazem, glyceryl trinitrate, nifedipine, minoxidil, and Lidocaine.
Methods: Following PRISMA guidelines, a systematic review and network meta-analysis were performed.
Flower-like Biomimetic Enzyme for Rapid and Sensitive Detection of Zearalenone in Vegetable Oil Deodorizer Distillate.

In order to achieve high quality production of vitamin E and plant sterols, it is necessary to conduct rapid and accurate detection of fungal toxins in their production raw material (vegetable oil deodorizer distillate, VODD). In this study, the flower-like biomimetic enzyme of silver-doped ZnO was synthesized through wet chemical method and in-situ reduction method. Based on above work, a flower-like biomimetic enzyme modified glass carbon electrode was fabricated, and its excellent detection capability against fungal toxins zearalenone was confirmed through electrochemical analysis.

Globally, drug-impaired driving fatalities now exceed those from drunk driving, urging the need for on-site and roadside detection methods. In this study, a photothermal desorption and reagent-assisted low-temperature plasma ionization miniature ion trap mass spectrometer (PDRA-LTP-ITMS) was developed for on-site detection of drug-impaired driving. The pseudomultiple reaction monitoring (MRM) in PDRA-LTP-ITMS enables continuous ion selection during ion introduction and improved sensitivity to nearly 3-fold compared with the conventional full scan mode.
