Silver impregnation methods are essential in biopsy interpretation in nephropathology with regard to visualizing the basal lamina and its associated changes. The most widely used methods, mainly Jones methenamine impregnation, are time-consuming in their protocols and require multiple microscopy control points. In this report, we propose an alternative, modified method for silver impregnation with methenamine solution with a significantly shorter protocol time and good staining quality, allowing for proper interpretation of basal lamina changes in the glomeruli and blood vessels. Furthermore, unlike some other modified techniques, our proposed protocol does not include microwaving of the solutions but rather a thermostat is used, thereby reducing fire hazards. Implementing the protocol in our everyday practice has reduced sample processing time while not negatively impacting biopsy interpretation.

Purpose: Biofilms are one of the main threats related to bacteria. Owing to their complex structure, in which bacteria are embedded in the extracellular matrix, they are extremely challenging to eradicate, especially since they can inhabit both biotic and abiotic surfaces. This study aimed to create an effective antibiofilm nanofilm based on graphene oxide-metal nanoparticles (GOM-NPs).

Despite the advances in the development of therapeutic wearable wound-healing patches, lack self-healing properties and strong adhesion to diabetic skin, hindering their effectiveness. We propose a unique, wearable patch made from a 3D organo-hydrogel nanocomposite containing polydopamine, titanium dioxide nanoparticles, and silver quantum dots (PDA-TiO@Ag). The designed patch exhibits ultra-stretchable, exceptional-self-healing, self-adhesive, ensuring conformal contact with the skin even during movement.

Simultaneous monitoring of antimicrobial responses to bacterial metabolic activity and biofilm formation is critical for efficient screening of new anti-biofilm drugs. A microbial fuel cell-based biosensor using as an electricigen was constructed. The effects of silver nanoparticles (AgNPs) on the cellular metabolic activity and biofilm formation of in the biosensors were investigated and compared with the traditional biofilm detection method.
