Summary: This study developed a hydrothermal synthesis of catechol formaldehyde resins (CFR) and silver nanoparticles (Ag NPs) from catechol, hexamethylenetetramine, and AgNO3, and constructed a coating called Ag/CFR in situ on the surface of cotton, polyester, polyamide, and their blended fabrics. The modified fabrics showed high antimicrobial activity with superior laundering durability, achieving a bacteriostasis and fungistasis rate of 99.99% even after 50 laundering cycles against S. aureus, E. coli, and C. albicans. The Ag/CFR coatings had minimal effects on the mechanical properties, air permeability, and feel of the fabric. This work provides an efficient and versatile approach for producing durable coatings for antimicrobial fabrics, which can be widely applied to clothing, bedding, and decorations.

Summary: Fabricating a multifunctional superhydrophobic cotton fabric with antibacterial properties is highly desirable but rare. This study proposes a one-step redox reaction strategy based on PMHS and [Ag(NH3)(2)](+) ions to endow cotton fabrics with superhydrophobic and antibacterial properties. The modified cotton fabrics exhibit high repellency against common liquids and significant antibacterial activity. The stability of the modified cotton fabrics, even under various treatments, makes them highly desirable for long-lasting anti-fouling, oil/water separation, and antibacterial applications.

Summary: The study investigates the photophysical properties and molecular docking interactions of acridine-based fluorophores with Bovine Serum Albumin (BSA) and non-narcotic drugs phenylbutazone (PB) and flufenamic acid (FA) in aqueous solution. It reveals that PB and FA displace the acridinedione (AD) dyes from specific binding sites in BSA, while the dyes prefer multiple binding sites in the presence of FA and PB. The combination of fluorescence tools with molecular modeling techniques is effective in determining the stability and binding characteristics of these complexes in a micro heterogeneous environment.

Summary: Despite progress, silver nanoparticles (AgNPs) have not yet reached clinical trials and show both positive and negative effects in toxicity. Convincing evidence for the synergistic bioactivities and diminished toxicity of capped (bio)molecules is lacking. This review highlights recent in vivo toxicity studies on chemically manufactured AgNPs, biologically synthesized AgNPs, and reference AgNPs, comparing their toxic effects and discussing overlooked factors leading to potential conflicts. Suggestions are given for better designing and conducting future toxicity studies and fast-tracking the clinical translation of AgNPs.

Summary: Photophysical studies were conducted on resorcinol-based ADR dyes in water with a glycoprotein OVA, revealing a red shift and slight increase in fluorescence intensity when OVA was added to PET-based dye ADR1. PET lifetime component increased significantly with the introduction of OVA, leading to the formation of multiple lifetime components. The presence of at least two different microenvironments of dye in the aqueous phase upon addition of OVA was confirmed.

Summary: Plastics and microplastics are widely present and accumulating in the environment, leading to increasing public attention. In addition to packaging plastics, materials from industries such as electronics, space and aviation are also accumulating, but receiving less attention. The production of degradable and biodegradable plastics is seen as a way to reduce environmental impacts, but enhancing the non-degradability of functional polymers is also a feasible option. Microbial colonization and deterioration pose significant challenges to these materials.

Summary: This study evaluated the keratinolytic activity of 37 strains of Trichophyton ajelloi and found that pigmented strains isolated from loamy soil were more efficient in degrading native feather keratin, while non-pigmented strains isolated from chernozem showed better abilities. The keratinolytic activity increased over time, as evidenced by the increase in extracellular keratinase activity and release of soluble proteins and peptides. Protease activity peaked in the first 7 days and again on day 28 of culture. The release of ammonium and sulfate ions, associated with an increase in pH, reached its maximum on day 21. Three pigment-producing strains were among the most active in releasing large amounts of ammonium and sulfate ions. The biodegradation of feather waste by Trichophyton ajelloi strains can be used to produce fertilizers suitable for plants with high sulfur requirements.
