Chemotherapy resistance remains a large obstacle to successful clinical cancer therapy, mainly due little accumulation and low sensitivity of drugs the effective strategy still lacks. Herein, novel yet simple combat drug using plasmonic feature‐based photothermal properties is reported. Rather than directly killing cells nanoparticle‐mediated hyperthermia, for first time, localized heating gold nanorod at mild laser power density can modulate drug‐resistance related genes. This effect...
The clearance of nanoparticles (NPs) by mononuclear phagocyte system (MPS) from blood leads to high liver and spleen uptake negatively impacts their tumor delivery efficiency. Here we systematically evaluated the in vitro vivo nanobio interactions a two-dimensional (2D) model, gold (Au) nanorings, which were compared with Au nanospheres nanoplates similar size. Among different shapes, nanorings achieved lowest MPS highest accumulation. sizes, 50 nm showed In addition, demonstrated potential...
Photothermal nanoplatforms with small size, low cost, multifunctionality, good biocompatibility and in particular biodegradability are greatly desired the exploration of novel diagnostic therapeutic methodologies. Despite Fe3O4 nanoparticles (NPs) have been approved as safe clinical agents, molar extinction coefficient subsequent poor photothermal performance shed doubt effective materials. In this paper, we demonstrate fabrication polypyrrole (PPy)-enveloped NP superstructures a spherical...
Abstract Uncontrollable bleeding from military conflicts, accidents, and surgical procedures is a major life‐threatening factor. Rapid, safe, convenient hemostasis critical to the survival of patients in prehospital care. However, peel‐off hemostats such as kaolinite sheets cotton fibers often poses risk distal thrombosis. Here, an efficient clay hemostat halloysite nanotubes tightly bound onto commercial fibers, which capillary mediated by biopolymer alginate with Ca 2+ crosslinking. The...
The screen-printing process of conductive ink can realize simple and large-scale manufacture micro/nano patterns for producing wearable electronic products. Herein, chitin nanocrystals (ChNCs) are used as a dispersant the preparation multiwalled carbon nanotube (MWCNT) with high viscosity uniformity by ultrasound treatment. ChNCs interact MWCNT in noncovalent ways, including π-π hydrophobic interactions. ChNCs/MWCNT (CCNT) does not aggregate even after standing 3 months maximum concentration...
A high-performance biodegradable plastic was made from a chitin KOH/urea solution. The solution transferred into hydrogel by cross-linking using epichlorohydrin and ethanol immersion, bioplastic finally prepared drying in mold at 40 °C. concentration positively impacts viscosity, crystallinity, smoothness. 4% exhibits high barrier properties, flame retardancy, high-temperature resistance, mechanical properties (tensile strength up to 107.1 MPa), soil degradation properties. can be completely...
Metal and metal-oxide nanoparticles (NPs) are promising catalysts for dye degradation in wastewater treatment despite the challenges of NP recovery recycling. In this study, water-dispersible superstructures with spherical morphology were constructed from hydrophobic Pd Fe3O4 NPs by virtue oil droplets an oil-in-water microemulsion as templates. Control evaporation rate organic solvents produces solid, hollow, bowl-like superstructures. The component particular can catalyze H2O2 to create...
Polyurethane (PU) sponge with high elasticity and reproducibility shows promising application in flexible electronic devices. However, the poor conductivity flammability limit its field, which also pose a potential threat to human health. Here, sensor based on PU polypyrrole-wrapped halloysite nanotubes (PPy@HNTs) was successfully fabricated by dip coating technology. The PPy-modified HNTs showed strong binding ability employing N,N-dimethylformamide (DMF) as an interfacial solvent. PPy@HNTs...
