Breaking resistance to nanoantibiotics by overriding corona-dependent inhibition using a pH-switch

Abstract: Nanoparticles are investigated as novel antibiotics, but are often inefficient in practical applications. We show from in situ to in vitro to in vivo that the bactericidal activity of metal-based nanoparticles but not microparticles against multidrug-resistant clinical isolates (MDR) strongly depends on physical binding to pathogens. Using controllable nanoparticle models, we report that nanoparticlebacteria …

Material solutions for delivery of CRISPR/Cas-based genome editing tools: Current status and future outlook

Abstract: Clustered regularly interspaced short palindromic repeat (CRISPR)/associated protein (CRISPR/Cas) system is an adaptable immune mechanism used by many bacteria to protect themselves from invading nucleic acids, and it has been recently exploited as an efficient tool for site-specific, programmable genome editing in both single cells and whole organisms with a precise manner. CRISPR/Cas system …

Tribology of two-dimensional materials: From mechanisms to modulating strategies

Abstract: Two-dimensional (2D) materials are crystalline materials made of a single or a few layers of atoms. They have been an active research subject in recent years because of their unique physical and chemical properties. In particular, 2D materials such as graphene, hexagonal BN, and MoS2 exhibit some of the lowest friction coefficients and wear …

Ultrathin Fresnel lens based on plasmene nanosheets

Abstract: Ultrathin Fresnel lens may revolutionize current optical imaging system, leading to thinner and lighter optoelectronic devices with a myriad of technical applications. To date, evaporated bulk metal films and top-down grown graphene represent viable material choices toward the design of ultrathin Fresnel lenses. Despite recent advances, it is still lack of a scalable fabrication …
