Wool powder assisted colorimetric sensing yarn with high sensitivity for NH monitoring.
Biosens Bioelectron
January 2025
Article Synopsis
- Colorimetric sensors are useful for gas monitoring as they detect gas presence through visible color changes, but creating highly sensitive versions has been a challenge.
- This study developed a sensitive colorimetric sensing yarn by combining anthocyanins dye with wool powder, significantly enhancing its sensitivity to ammonia (NH) gas.
- The yarn's detection limit improved from 100 ppm to 20 ppm, and the response time decreased from 2 minutes to just 20 seconds, showcasing potential for effective toxic gas monitoring in wearable devices.
Preparation of chitin twisted fiber and its functional applications.
Int J Biol Macromol
October 2024
Article Synopsis
- Chitin is a sustainable material known for its biocompatibility and biodegradability, but its practical uses are limited due to performance deficiencies.
- Researchers developed a multi-step method to create high-performance chitin fibers using techniques like chemical pre-crosslinking, wet-twisting, and wet-stretching, resulting in strong fibers with adjustable properties.
- The addition of functional particles like FeO or Ag allows the fibers to gain magnetic or conductive properties without compromising their strength, providing a solution for integrating organic and inorganic materials.
Cellulose beads were successfully prepared from waste denim using a dissolution-regeneration approach with ionic liquids as the dissolving solvent. Cellulose beads with different morphologies were achieved by altering the dissolving and coagulating solvents. The morphological differences were quantified by N physisorption.

Cellulose aerogels with orientated micron-sized pore structure were obtained from denim waste utilizing ionic liquid solvents through dissolution, regeneration and drying. The pore structure of denim-derived aerogels was comprised of a mixture of micron-sized vertically aligned pores and a nanoporous fibrous network. The size and distribution of vertically aligned pores and the nanopores were influenced by the choice of ionic liquid solvent, amount of denim used and drying method employed.

Here, we evaluated the efficacy of an antithrombotic drug, suloctidil, against biofilms and . We found that suloctidil is effective to inhibit biofilm, with a minimum inhibitory concentration (MIC) of 4 μg/mL, a biofilm inhibiting concentration (BIC) of 16 μg/mL and a biofilm eradicating concentration (BEC) of 64 μg/mL.

Although point mutations in the 23S rRNA are key factors for CLA resistance, other factors, including efflux pumps and regulation genes, are also involved in the resistance of to CLA.
