Microplate Active Migration Emerging From Light‐Induced Phase Transitions in a Nematic Liquid Crystal

Advanced Functional Materials, EarlyView.
A quasi‐2D, light‐absorbing platelet embedded in a thermotropic nematic liquid crystal is activated with light irradiation. Depending on the light intensity, the platelet induces a localized nematic‐isotropic phase transition that triggers the motion. Using different confinements, the platelet can glide in a 2D regime or tilt and glide in a 3D regime ...

Microbubble‐Controlled Delivery of Biofilm‐Targeting Nanoparticles to Treat MRSA Infection

Advanced Functional Materials, EarlyView.
Here, an effective strategy using microbubble (MB)‐controlled delivery of biofilm‐targeting nanoparticles (BTNs) for removal and therapy of methicillin‐resistant Staphylococcus aureus (MRSA) biofilm infections is introduced. In vivo delivery of MB with BTN is demonstrated to silence key bacterial genes involved in biofilm formation (icaA), bacterial ...

Kidney Stone Dissolution By Tetherless, Enzyme‐Loaded, Soft Magnetic Miniature Robots

Advanced Healthcare Materials, EarlyView.
Wireless magnetic robots are developed for kidney stone dissolution. The robots navigate through a urinary tract model from bladder and ureter to renal pelvis with the help of external magnetic fields. The filaments are loaded with urease enzyme which catalyzes urea to carbon dioxide and ammonia, thereby increasing pH to basic regime and supporting ...

Nanobody‐Decorated Lipid Nanoparticles for Enhanced mRNA Delivery to Tumors In Vivo

Advanced Healthcare Materials, EarlyView.
This study presents a targeted mRNA‐LNP platform engineered with anti‐PSMA nanobodies for prostate cancer therapy. Using different in vivo models, the authors demonstrate selective uptake and mRNA delivery in PSMA+ cancer cells. However, while targeting is enhanced, mRNA delivery efficacy is limited by tissue penetration, tumor necrosis, and immune ...
