Negative linear compressibility and structural stability of the energetic material -hexanitrostilbene under pressure.

The structural stability of the energetic material 2,2',4,4',6,6'-hexanitrostilbene (-HNS) under high pressure is critical for optimizing its detonation performance and low sensitivity. However, its structural response to external pressure has not been sufficiently investigated.

Ultrasound-triggered drug-loaded nanobubbles for enhanced T cell recruitment in cancer chemoimmunotherapy.

Chemotherapy combined with immunotherapy is a highly promising approach for treating tumors. However, chemotherapeutic drugs often fail to accumulate effectively at the tumor site after systemic administration and they lack sufficient immunogenicity to activate adaptive immunity, making an effective T-cell immune response within the tumor microenvironment difficult to achieve. Here, this work developed drug-loaded nanobubbles (DTX-R837@NBs) that encapsulate the chemotherapy drug docetaxel and the immune adjuvant R837 via a thin-film hydration method.

Efficient gene delivery admitted by small metabolites specifically targeting astrocytes in the mouse brain.

The development of efficient and targeted methods for delivering DNA in vivo has long been a major focus of research. In this study, we introduce a gene delivery approach admitted by small metabolites (gDAM) for the efficient and targeted delivery of naked DNA into astrocytes in the adult brains of mice. gDAM uses a straightforward combination of DNA and small metabolites, including glycine, L-proline, L-serine, L-histidine, D-alanine, Gly-Gly, and Gly-Gly-Gly, to achieve astrocyte-specific delivery of naked DNA, resulting in transient and robust gene expression in these cells.
