Multidimensional In Situ Characterization of Surface and Free Nanobubbles in Oxidic Nanofluids

Powders
The efficiency of froth flotation drastically drops towards ultrafine particles. Some improvements may be possible using smaller bubbles and high degrees of turbulence, however, reaching their limits in the nanometer particle range.

ROS‐Responsive Nanobubbles for Dual‐Enhanced Ultrasound and Magnetic Resonance Imaging of Tumor Oxidative Stress

Advanced Science, EarlyView.
We report the development of biotinylated PEGylated bilirubin‐coated perfluoropentane (bt‐PEG‐BR@PFP) nanobubbles, a novel class of ROS‐activatable and dual‐modality contrast agents that amplify both ultrasound (US) and magnetic resonance imaging (MRI) signals in response to elevated ROS.

Femtosecond‐Laser Nanocavitation Regenerates SERS‐Active Plasmonic Nanogaps for Longitudinal Molecular Sensing at Biointerfaces

Advanced Science, EarlyView.
A regenerative molecular sensing platform that co‐localizes surface‐enhanced Raman spectroscopy (SERS) sensing and nanocavitation‐based actuation. Femtosecond‐laser triggered nanocavitation produces thermomechanical forces to locally regenerate SERS‐active nanogaps in protein‐rich biofluids while preserving optical performance.

Spatiotemporally Ultrasound‐Controlled Nanoparticles Reprogramming Immunostimulatory Antigen‐Presenting Cancer‐Associated Fibroblasts to Enhance Cancer Immunotherapy

Advanced Science, EarlyView.
We developed an ultrasound‐controlled biomimetic nanoplatform, mRNA/V@M NPs, to co‐deliver CD74 mRNA and V‐9302 for fibrotic TNBC therapy. CD74 mRNA reprograms myCAFs into antigen‐presenting apCAF cells through the CD74‐MHC II pathway, while V‐9302 induces ICD and activates MHC I‐CD8+ T cell immunity.
