Silver‐enhanced Photoresponsive g‐C3N4/Ag Janus Microrobots With Negative Photogravitaxis Efficient Antibiotic Degradation

open access: yesSmall, EarlyView.
ABSTRACT Water pollution remains a serious global challenge; hence, the efficient, low‐cost, and environmentally friendly removal of pollutants from water has become a research hotspot. Photocatalytic microrobots can achieve autonomous movement and generate reactive oxygen species (ROS), presenting a great opportunity for water purification.

Do We Really Know Why Carbon Nanotubes Grow?

open access: yesSmall, EarlyView.
The CNT growth mechanism is still debated. We propose a heterogeneous (2D) classical nucleation framework comparing pathways for graphenic patches, caps, and full CNTs. Despite its simplicity, it rationalizes key trends, including the correlation between catalyst particle size and CNT diameter.

Selective Lipoprotein Removal Enables High‐Purity EV Isolation from Plasma via Aptamer‐Based Mesh Filtration

open access: yesSmall, EarlyView.
A novel affinity‐based mesh filtration system, ApoFilter, enables selective removal of plasma lipoproteins via sequential aptamer‐functionalized layers targeting ApoA1 and ApoB100. While EVs pass through unimpeded, (V)LDL and HDL are rapidly depleted.
