Here we report that silver nanoparticle necklaces can be readily formed by treatment of colloidal silica with ammoniacal silver complex solution followed by washing, deposition and ageing. We investigate the morphology of the produced materials and elucidate the key variables that influence this promising new approach to one-dimensional nanostructuring.

Integrating noble metal nanostructures, specifically silver nanoparticles, into sensor designs has proven to enhance sensor performance across key metrics, including response time, stability, and sensitivity. However, a critical gap remains in understanding the unique contributions of various synthesis parameters on these enhancements. This study addresses this gap by examining how factors such as temperature, growth time, and choice of capping agents influence nanostructure shape and size, optimizing sensor performance for diverse conditions.

Extraintestinal (ExPEC), known to be the most common instigators of urinary tract infections (UTIs), represent such global threat. Novel strategies for more efficient treatments are therefore desperately needed.

Purpose: Multi-walled carbon nanotubes (MWCNTs) were used as carriers for silver nanoparticles (AgNPs). In this process, MWCNTs were coated with mesoporous silica (MWCNT-Silica) for uniform and regular loading of AgNPs on the MWCNTs. In addition, astaxanthin (AST) extract was used as a reducing agent for silver ions to enhance the antioxidant, antibiofilm, and anticancer activities of AgNPs.

The accurate and reliable quantification of the levels of disease markers in human sweat is of significance for health monitoring through wearable sensing technology, but the sensors performed in real sweat always suffer from biofouling that cause performance degradation or even malfunction. We herein developed a wearable antifouling electrochemical sensor based on a novel multifunctional hydrogel for the detection of targets in sweat. The integration of polyethylene glycol (PEG) into the sulfobetaine methacrylate (SBMA) hydrogel results in a robust network structure characterized by abundant hydrophilic groups on its surface, significantly enhancing the PEG-SBMA hydrogel's antifouling and mechanical properties.

The effectiveness and safety of hemodialysis can be hindered by protein accumulation, mechanical instability of membranes and bacterial infection during the dialytic therapy. Herein, we show that cellulose acetate membranes modified with the low-fouling polymers (namely polyvinylpyrrolidone and polyethylene glycol), followed by the in situ reduction of different densities of silver oxide(I) nanoparticles, can effectively address these limitations. These improvements comprise the enhanced resistance to the protein fouling, improved antimicrobial capabilities against S.
