Ciprofloxacin-loaded thermosensitive hydrogels composed of silk fibroin and poloxamers were prepared using the cold method. F1, F2, and F3 formulations resulted in gelation time of within 3 min under 37°C. Physical evaluation showed that the formulations, especially F3, had a proper swelling ratio and 82.34% biodegradability within 14 days. Ciprofloxacin from formulations exhibited an initial burst release within 24 h and continuous delivery, with more than 84% release over 14 days. Released antibiotics showed efficacy against <jats:italic>Staphylococcus aureus</jats:italic> ATCC25923 and eradicating activity against biofilms. Moreover, hydrogels had no cytotoxic effect on MC3T3-E1 cells with 93–106% cell viability.

It is a distinctive configuration of yarn’s constituents and the EF draft that are responsible for the exceptional stretchability of yarns, and it showed mechanical robustness following cyclic stretch. Importantly, the yarn exhibited rapid, durable, and reversible color conversion when subjected to cyclic voltage, cyclic abrasion, and alkali.

Meanwhile, researchers are focused on improving the EMS efficiency of the fabric but rarely discussed the thermal-wet comfort of the fabric. Therefore, in this study a series of weft-knitted fabrics within stainless steel/cotton (30/70) blended yarns were knitted, and the effects of EMW incident direction, stitches, loop lengths, and frequency on EMS effectiveness (EMSE) were analyzed. Meanwhile, the EMS property, warmth retention property, air permeability, moisture permeability, and bursting strength were selected as the evaluation index to evaluate the comprehensive properties of the fabrics by fuzzy mathematics. The results showed that all factors had different degrees of influence on EMSE, and the weft inlay stitch had both the functionality and thermal-wet comfort, which was excellent EMSE in knitted fabric.

The present work describes the creation of core–shell nanoparticles as a biosensor for smart enzyme detection of salivary alpha-amylase (sAA). A chitosan-tripolyphosphate core was generated via ionic gelation and was coated with a starch–iodine shell to create biocompatible core–shell nanoparticles. The starch–iodine shell was ruptured in the presence of certain amounts of amylase, exposing the core. This application explains a noticeable color change from blue to white that can be used to identify sAA at the point of care. Synthesized nanoparticles were examined for scanning electron microscopy analysis and energy-dispersive X-ray (EDX). An EDX report reveals that the nanoparticles have higher carbon content at 55% followed by an oxygen atom of 35%. Fourier-transform infrared spectroscopic analysis revealed that the core–shell nanoparticles have carbonyl (C═O) functional groups present. A confirmatory test of amylase reaction on nanoparticle-impregnated paper turns blue to white indicating that the nanoparticle reacts with amylase as an indicator.
