The electrical conductivity and antibacterial properties are crucial characteristics for bacterial cellulose (BC) based membranes to be broadly applied in the field of wearable electronics. In the study, to achieve these aims, alpha-lipoic acid (LA) was utilized as anchoring groups and reducing agent, hydroxypropyl-β-cyclodextrin (HP-β-CD) capped magnetic particles (FeO NPs) and the in-situ formed silver nanoparticles (AgNPs) were sequentially incorporated into the BC matrix to fabricate BC based nanocomposite membranes (HP-β-CD/FeO/LA@BC and HP-β-CD/FeO/LA/Ag@BC). Fourier transform attenuated total reflectance infrared spectroscopy (FTIR-ATR) and field emission scanning electron microscopy (FE-SEM) analysis proved the dense networks were formed in the modified BC membranes.

Microplastics (MPs), defined as plastic particles smaller than 5 mm, have garnered considerable attention owing to their potential biological impact on human health. These particles exhibit a range of physicochemical properties, including size, shape, and surface oxidation. Nile Red is a prominent tool for detecting microplastics, enabling staining for dynamic analyses within biological systems.

Retinal ganglion cell (RGC) protection represents an unmet need in glaucoma. This study assessed the neuroprotective, antioxidant, and anti-inflammatory effect of a new nutraceutical formulation named Epicolin, based on citicoline, homotaurine, epigallocatechin-3-gallate, forskolin, and vitamins, through in vitro and in vivo studies. The neuroprotective effect of Epicolin or its single components, and Epicolin compared to an untreated control and two marketed formulations [Formulation G (FG) and N (FN)], was evaluated in neuroblastoma cells (SH-SY5Y) challenged with staurosporine.

In this research, poly(lactic acid) (PLA) nanocomposites with multi-walled carbon nanotubes (MWCNT) were produced by extrusion, injection, and compression molding, focusing on electromagnetic shielding. Various amounts of carbon nanotubes (MWCNTs) were tested in PLA matrix, specifically ranging from 1 to 4 parts per hundred resin (phr). The resulting nanocomposites were analyzed before and after undergoing annealing heat treatment.
