Synthesis and characterization of CDots On this examine, carbon dots (CDots) have been synthesized by a one-step microwave method utilizing ascorbic acid and PEI [16]. Beneath daylight, the as-prepared CDots options exhibited a pale yellow, remodeling right into a shiny blue photoluminescence (PL) underneath ultraviolet (UV) radiation (Fig. 1A). The CDots options’ PL spectrum had a…

In a current article revealed in Scientific Studies, researchers introduced a composite wound dressing composed of polylactic acid (PLA), curcumin, and carbon nanotubes (CNTs), designed to enhance mechanical energy and antibacterial exercise. The dressing was fabricated utilizing electrospinning, with CNTs included to boost curcumin launch and maintain antibacterial effectiveness via nanoscale structural management. Picture Credit…

Credit score: ACS Nano (2025). DOI: 10.1021/acsnano.4c15441 A joint analysis workforce has developed a modular protein adapter know-how that permits the steady attachment of assorted substances to the floor of extracellular vesicles (exosomes). It was designed to allow useful molecules to bind effectively, even within the complicated environments of cell membranes. The analysis demonstrated the…

If you have not heard of a tardigrade earlier than, put together to be wowed. These clumsy, eight-legged creatures, nicknamed water bears, are about half a millimeter lengthy and might survive virtually something: freezing temperatures, close to hunger, excessive strain, radiation publicity, outer house and extra. Researchers reporting in ACS’ Nano Letters took benefit of…
