AbstractCarbon dots tend to aggregate into clusters during lyophilisation, and the obtained powder is highly hygroscopic not easy store. This study introduces a simple way solve it. Hydroxypropyl methyl cellulose(HPMC)was selected enhance stability of carbon dot after freeze-dried. Firstly, an interesting had been prepared from L-arginine via hydrothermal method, which showed certain antibacterial properties towards E. coli S.aureus. Secondly, mixing aqueous solution with HPMC according mass ration stirred evenly. Put mixture freeze drying oven until dried, got powder, was tested by XPS IR. The results demonstrated that content surface element in has changed owned characteristics HPMC. developed exhibited similar optical those solutions emitted significant blue fluorescence when irradiated ultraviolet lamp. Importantly, solid high under ambient temperatures. It stable storage for up one year no longer hygroscopic.

Carbon dots (CDs) are novel carbon-based nanomaterials that have been used as photosensitizer-mediated photodynamic therapy (PDT) in recent years due to their good photosensitizing activity. Photosensitizers (PSs) main components of PDT can produce large amounts reactive oxygen species (ROS) when stimulated by light source, which the advantages low drug resistance and high therapeutic efficiency. CDs generate ROS efficiently under irradiation therefore extensively studied disease local phototherapy. In tumor therapy, be PSs or PS carriers participate play an extremely important role. bacterial infectious diseases, exhibit bactericidal activity effective disrupting cell membranes leading death upon photoactivation. We focus on advances cancer bacteria with CDs, also briefly summarize mechanisms requirements for cancer, other diseases. discuss role combination potential future applications against pathogens.

Carbon dots (CDs), a class of carbon-based nanomaterials with dimensions less than 10 nm, have attracted significant interest since their discovery. They possess numerous excellent properties, such as tunability photoluminescence, environmental friendliness, low cost, and multifunctional applications. Recently, large number reviews emerged that provide overviews synthesis, applications, composite functionalization. The application CDs in the field optoelectronics has also seen unprecedented development due to optical but them this are relatively rare. With idea deepening broadening understanding applications optoelectronics, review for first time provides detailed summary luminescent solar concentrators (LSCs), light-emitting diodes (LEDs), cells, photodetectors. In addition, definition, categories, synthesis methods briefly introduced. It is hoped can bring scholars more deeper optoelectronic further promote practical CDs.

Abstract Ischemic stroke is a complex, high-mortality disease with multifactorial etiology and pathogenesis. Currently, drug therapy mainly used treat ischemic in clinic, but there are still some limitations, such as limited blood-brain barrier (BBB) penetration efficiency, narrow treatment time window side effects. Recent studies have pointed out that delivery systems based on polymeric nanocarriers can effectively improve the insufficient for stroke. They provide neuronal protection by extending plasma half-life of drugs, enhancing drug’s permeability to penetrate BBB, targeting specific structures cells. In this review, we classified delivering drugs introduced their preparation methods. We also evaluated feasibility effectiveness discussed existing limitations prospects treatment. hoped review could theoretical basis future development nanomedicine Graphical

Abstract Sepsis is a life‐threatening condition that can progress to septic shock as the body's extreme response pathogenesis damages its own vital organs. Staphylococcus aureus ( S. ) accounts for 50% of nosocomial infections, which are clinically treated with antibiotics. However, methicillin‐resistant strains (MRSA) have emerged and withstand harsh antibiotic treatment. To address this problem, curcumin (CCM) employed prepare carbonized polymer dots (CPDs) through mild pyrolysis. Contrary curcumin, as‐formed CCM‐CPDs highly biocompatible soluble in aqueous solution. Most importantly, induce release neutrophil extracellular traps (NETs) from neutrophils, entrap eliminate microbes. In an MRSA‐induced mouse model, it observed efficiently suppress bacterial colonization. Moreover, intrinsic antioxidative, anti‐inflammatory, anticoagulation activities resulting preserved functional groups precursor molecule on prevent progression severe sepsis. As result, infected mice show significant decrease mortality even oral administration. Histological staining indicates negligible organ damage MRSA‐infected CCM‐CPDs. It believed vivo studies presented herein demonstrate multifunctional therapeutic CPDs hold great potential against infectious diseases.
