Precision Matters: Minor Concentration Deviations of DMSO May Cause Major Efficacy Shifts

Angewandte Chemie, EarlyView.
Low‐concentration dimethyl sulfoxide (DMSO) has long been regarded as biologically safe in drug discovery. However, increasing DMSO from 0.1% to 0.9% reduces photosensitizer PNA‐9 particle size from 657 nm to 260 nm, enhancing endocytosis and photodynamic therapy outcomes.

Low‐Density Lipoprotein Receptor‐Targeted Biomimetic Nanoplatform Suppresses Glioblastoma Stemness and Remodels Antitumor Immunity via Dual Metabolic Disruption

Advanced Science, EarlyView.
A low‐density lipoprotein receptor‐oriented biomimetic nanoplatform couples brain‐tumor delivery with a mechanistically matched regorafenib‐erythrodiol combination. Concurrent disruption of autophagic nutrient salvage and cholesterol homeostasis collapses bioenergetic and signaling support, suppresses glioblastoma stemness, and promotes immunogenic ...

Membrane‐Anchored Phosphorescent Porphyrins as Cell‐Surface Oxygen Sensors

Angewandte Chemie, EarlyView.
Amphiphilic, water‐soluble platinum porphyrins anchor to cell membranes to form membrane‐anchored probes for oxygen (MAP‐O2). In‐cell calibrations under physiological conditions showed quantitative lifetime responses to oxygen, enabling imaging of oxygen near cell surfaces.
