Outer membrane vesicles (OMVs) are spherical structures that contain a small fraction of the periplasm Gram-negative bacteria, surrounded by its outer membrane. They naturally produced and detached from bacterial surface, participate in diverse biological processes, their diameter size is range 10–300 nm. OMVs have gained interest different applications, such as development biosensors, vaccines, protein chips, encapsulation heterologous proteins peptides expressed these microorganisms. However, use applications limited due to low yields high purification costs. In this study, we green fluorescent (GFP) encapsulated into using Escherichia coli JC8031 transformed with pTRC99A-ssTorA-GFP establish production route. Results showed motility strain prevents immobilization alginate, which hampers OMVs. To address issue, zeolite-based column was used chromatographically separate smaller particles. Further experiments will be focused on standardizing at scalable level.

Nanotheranostics—where nanoscale materials serve both diagnostic and therapeutic functions—are rapidly transforming gene therapy by tackling critical delivery challenges. This review explores the design engineering of various nanoparticle systems (lipid-based, polymeric, inorganic, hybrid) to enhance stability, targeting, endosomal escape genetic payloads. We discuss how real-time imaging capabilities integrated into these platforms enable precise localization controlled release genes, improving treatment efficacy while reducing off-target effects. Key strategies overcome barriers (such as proton sponge effect photothermal disruption) achieve nuclear are highlighted, along with recent advances in stimuli-responsive that facilitate spatiotemporal control expression. Clinical trials preclinical studies demonstrate expanding role nanotheranostics managing cancer, inherited disorders, cardiovascular neurological diseases. further address regulatory manufacturing hurdles must be for widespread clinical adoption nanoparticle-based therapies. By synthesizing progress ongoing challenges, this underscores transformative potential effective, targeted, image-guided delivery.

Exposure to high temperatures during indoor and outdoor activities increases the risk of heat-related illness such as cramps, rashes, heatstroke (HS). Fatal cases HS are ten times more common than serious cardiac episodes in sporting scenarios, with untreated leading mortality rates 80%. Enhancing thermal comfort can be achieved through heat loss enclosed spaces human body, utilizing transfer mechanisms radiation, conduction, convection, evaporation, which do not require initial energy input. Among these, two primary commonly employed textile industry enhance passive cooling: radiation conduction. The approach encompasses aspects: (1) reflecting solar spectrum (SS) wavelengths (2) transmitting emitting atmospheric window (AW). Conduction involves dissipating materials a conductivity. Our study focuses on combined effect these radiative conductive approaches increase loss, an area that has been extensively studied date. Therefore, main objective this project is develop, characterize, evaluate nanocomposite polymeric system using electrospinning, incorporating graphene oxide (GO) nanosheets titanium dioxide nanoparticles (TiO
