Disulfide bond (Dsb) proteins, especially DsbA, represent a promising but as-yet-unrealized target in combating multidrug-resistant (MDR) bacteria because their precise subcellular targeting through multibarrier remains a significant challenge. Here, a novel heterogenization-phase-separated nano-antibiotics (NCefoTs) is proposed, through the co-assembly of enzyme-inhibiting lipopeptides (ELp component), membrane-recognizing and disrupting lipopeptides (MLp component), and cefoperazone. The self-sorting components of MLp "concentrated island-liked clusters" on the surface of NCefoTs promote the efficient penetration of NCefoTs through the outer membrane.

Many low- materials exhibit unique properties, such as weak or even insignificant dependence on temperature () for , , an anomalous glass-like behavior. However, a comprehensive theoretical model elucidating the microscopic phonon mechanism responsible for the glass-like - relationship is still absent.

Herein, a new system, which can escape immune recognition, has HIV-1 neutralizing capacity, and the ability to deliver siRNA specifically into HIV-1-infected cells, is constructed by functionalizing siRNA delivery lipid nanoparticles with the lymphocyte membrane and 12p1. The constructed system is shown to escape uptake by the mononuclear phagocyte system.

In spintronics, the embodiment of abundance availability, long spin relaxation time, complete spin-polarization and high Curie temperature () in intrinsic metal-free half-metallic ferromagnets (MFHMFs) are highly desirable and challenging. In this work, employing density functional theory, we first propose a dynamically, thermally, and mechanically stable two-dimensional (2D) intrinsic MFHMF, a MoS-like PN monolayer, which possesses not only completely spin-polarized half-metallicity, but also an above-room-temperature (385 K). The half-metallic gap is calculated to be 1.
