Silk-polyurethane composite based flexible electrochemical biosensing platform for pathogen detection.

The upcoming era of flexible and wearable electronics necessitates the development of low-cost, flexible, biocompatible substrates amenable to the fabrication of active devices such as electronic devices, sensors and transducers. While natural biopolymers such as Silk are robust and biocompatible, long-term flexibility is a concern due to the inherent brittle nature of soft Silk thin films. This work elucidates the preparation and characterization of Silk-polyurethane (Silk-PU) composite film that provides long-duration flexibility.

Exploring time-killing and biofilm inhibition potential of bioactive proteins extracted from two varieties of .

Introduction: Dental caries, caused by oral microbial pathogens, are a global health concern, further exacerbated by the presence of methicillin-resistant (MRSA). Bioactive proteins and peptides (BAPs) exhibit potent antimicrobial properties, targeting multiple cellular mechanisms within pathogens, reducing the likelihood of resistance development. Given the antimicrobial potential of BAPs, this study aimed to compare the efficacy of BAPs extracted from cultivated (, PoC) and wild (, PoW) mushrooms against pathogens responsible for dental caries.

Treatment of textile dyes in a photo-surface dielectric barrier discharge hybrid reactor: Unraveling the degradation mechanisms.

The study demonstrates the unprecedented ability of UV-C integrated surface dielectric barrier discharge (photo-SDBD) in the rapid removal of azo (brilliant red X3B), direct (direct yellow - 44), and reactive dyes (turquoise blue H5G) in textile wastewater. The degradation mechanisms of these dyes were studied using a high-resolution mass spectrometer (HRMS), and a step-by-step reaction pathway was proposed. The BR-X3B and DY-44 dyes undergo azo bond dissociation followed by functional group rearrangement, ring opening, and formation of open chain intermediates.
