Cell-based drug carriers are mostly prepared in vitro, which may negatively affect the physiological functions of cells, and induce possible immune rejections when applied to different individuals. In addition, immunosuppressive tumor microenvironment limits cell-mediated delivery. Here, we report an vivo strategy construct cell-based nanomedicine carriers, where bacteria-mimetic gold nanoparticles (GNPs) intravenously injected, selectively phagocytosed by phagocytic subsequently...

Flexible tactile sensors show promise for artificial intelligence applications due to their biological adaptability and rapid signal perception. Triboelectric enable active dynamic sensing, while integrating static pressure sensing real-time multichannel transmission is key further development. Here, we propose an integrated structure combining a capacitive sensor spatiotemporal mapping triboelectric recognition. A liquid metal-based flexible dual-mode triboelectric-capacitive-coupled (TCTS)...

Abstract As many diseases are related to inflammation, the inflammatory tropism of immune cells may bring cell‐hitchhikers directly disease tissues in a highly targeted manner. The current cell‐hitchhiking strategies rely on either cellular internalization or covalent surface conjugation, which often affects physiological function transporting cells. Herein, cell‐friendly, host‐guest chemistry mediated macrophage‐liposome conjugate (M‐L) is developed for extremely stable drug delivery. M‐L...

Abstract Immune cells exhibit great potential as carriers of nanomedicine, attributed to their high tolerance internalized nanomaterials and targeted accumulation in inflammatory tissues. However, the premature efflux nanomedicine during systemic delivery slow infiltration into tissues have limited translational applications. Herein, a motorized cell platform carrier for highly efficient lungs effective treatment acute pneumonia are reported. β‐Cyclodextrin adamantane respectively modified...

Solid materials with different structure containing C and N were analyzed by laser-induced breakdown spectroscopy (LIBS). Comparing the emission molecular species in atmosphere (air argon), it can be determined that whether are directly vaporized from sample or generated through dissociation interaction between plasma air molecules. The results showed characteristic of C2 bands is similar neutral atomic carbon CI argon). While CN more complicated has great relationship existence radicals,...

Bone scaffolds are widely used as one of the main bone substitute materials. However, many scaffold microstructure topologies exist and it is still unclear which topology to use when designing for a specific application. The aim present study was reveal mechanism microstructure-driven performance thus provide guideline on design. Finite element (FE) models five TPMS (Diamond, Gyroid, Schwarz P, Fischer-Koch S F-RD) three traditional (Cube, FD-Cube Octa) were generated. effective compressive...

In this design, small CuS nanoparticles (NPs) were intracellularly self-assembled into large supramolecular aggregates via host-guest interactions between sequentially internalized β-cyclodextrin-capped NPs and ferrocene-capped inside macrophages, thus the efflux of was significantly inhibited during macrophage-hitchhiking delivery. Biodistribution studies in mice confirmed dramatically enhanced deposition tumor tissue injected with macrophages carrying intracellular aggregates, comparison...

Bacterial infection has become a global concern owing to the significant morbidity and mortality. Although phagocytosis of bacteria by immune cells acts as front line protect human body from invading pathogens, relatively slow encounter insufficient capture often lead an inefficient clearance pathogens. Herein, supramolecular artificial receptor-modified macrophage (SAR-Macrophage) was developed enhance recognition latch in systemic circulation, mediated via strong multipoint host-guest...

Abstract Mid-infrared (mid-IR) sensors consisting of silicon nitride (SiN) waveguides were designed and tested to detect volatile organic compounds (VOCs). SiN thin films, prepared by low-pressure chemical vapor deposition (LPCVD), have a broad mid-IR transparent region lower refractive index (n = 2.0) than conventional materials such as Si 3.4), which leads stronger evanescent wave therefore higher sensitivity, confirmed finite-difference eigenmode (FDE) calculation. Further, in-situ...

Laser-induced breakdown spectroscopy (LIBS) has been applied for the multi-elemental analysis of fertilizer. With a set 11 fertilizer samples containing different levels phosphorus and potassium, it was identified that line intensity analyte does not follow straightforward correlation with element concentration presence matrix effects. Instead, given is only related to analyte, but also other elements present in samples. Further reveals correlations among intensities main components. Based...
