Engineered macrophages are a promising tool for drug delivery and immunotherapy in cancer treatment. However, simultaneous targeted enrichment and controllable immunological activation of these macrophages at the tumor site remains challenging. As a solution, macrophages loaded with an advanced nanoparticle encapsulating CpG‐conjugated magnetic nanoclusters (MNC) with indocyanine green (ICG) and nigericin...
An investigation is presented into the effect of the long‐range order on the optoelectronic properties of PbS quantum dot (QD) superlattices, which form mesocrystals, for potential use in photodetector applications. By self‐assembly of QD nanocrystals on an Si/SiOx substrate, a highly ordered and densely packed PbS QD superlattice with a microscale size is obtained. The results demonstrate that annealing...
The protein corona effect has long been treated as the evil source behind delivery efficacy issues. In this study, this concept is challenged by showcasing that the protein corona can serve as a versatile functionalization approach to improve the delivery efficacy or mitigate nanocytotoxicity. To this end, the depleted serum is introduced to create nanomaterials carrying functionally distinct protein...
Point defects of heteroatoms and vacancies can activate the inert basal plane of molybdenum sulfide (MoS2) to improve its performance on catalyzing the hydrogen evolution reaction (HER). However, the synergy between heteroatoms and vacancies is still unclear. Here, a chemical vapor deposition‐assisted in situ vanadium (V) doping method is used to synthesize monolayer MoS2 with abundant and tunable...
Polymer‐based quasi‐solid‐state electrolyte (QSE) is an effective means to solve the safety problem of lithium (Li) metal batteries, and stable solid‐electrolyte‐interface (SEI) layers between electrolyte and anode/cathode are highly required for their long‐term stability. Herein, it is demonstrated that a silicon‐doped polyether functions as a multifunctional unit, which can induce the formation...
Although incorporating multiple halogen (bromine) anions and alkali (rubidium) cations can improve the open‐circuit voltage (Voc) of perovskite solar cells (PSCs), severe voltage loss and poor stability have remained pivotal limitations to their further commercialization. In this study, acetylcholine (ACh+) is anchored to the surface of a quadruple‐cation perovskite to provide additional electron...
Acute hepatitis is a major problem affecting public health and has attracted more and more attention. Generally, as the standard means, blood tests are taken for evaluating hepatitis. However, such tests fail to accurately reflect the level of hepatitis in vivo. Herein, two highly selective ratiometric fluorescent probes are designed to track peroxynitrite (ONOO−) as the hepatitis indicator, and further...
Over the last decades, the fabrication of 3D tissues has become commonplace in tissue engineering and regenerative medicine. However, conventional 3D biofabrication techniques such as scaffolding, microengineering, and fiber and cell sheet engineering are limited in their capacity to fabricate complex tissue constructs with the required precision and controllability that is needed to replicate biologically...
In article number 1805510, Yu Shrike Zhang and co‐workers systematically review the history of 3D bioprinting and its recent advances in instrumentation and methods. The requirements for bioinks and cells to achieve optimal fabrication of biomimetic constructs, emerging evolutions and future directions of bioprinting, translational potential of bioprinting and bioprinted tissues of various categories,...
A new class of solvent free, lyotropic liquid crystal nanocomposites based on gold nanorods (AuNRs) with high nanorod content is reported. Application of shear results in switchable, highly ordered alignment of the nanorods over several centimeters with excellent storage stability for months. For the synthesis, AuNRs are surface functionalized with a charged, covalently tethered corona, which induces...
A facet‐selective atomic layer deposition method is developed to fabricate oxide nanofence structure to stabilize Pt nanoparticles. CeOx is selectively deposited on Pt nanoparticles' (111) facets and naturally exposes Pt (100) facets. The facet selectivity is realized through different binding energies of Ce precursor fragments chemisorbed on Pt (111) and Pt (100), which is supported by in situ mass...
