Tumbling Magnetic Microrobots for Targeted In Vivo Drug Delivery in the GI Tract

Advanced Robotics Research, EarlyView.
We introduce a microrobot design and integrated system for on‐demand targeted drug release in the gastrointestinal tract. The microrobot has an embedded magnet for actuation with external magnetic fields and is visualized in real time using ultrasound. It has two drug release ports sealed with a thermally sensitive wax. Local heating of the wax using a

Waveguide Photoactuators: Materials, Fabrication, and Applications

Advanced Robotics Research, EarlyView.
Waveguide photoactuators convert guided light into mechanical motion. Their tethered‐flexible design enables minimally invasive surgery and confined‐space robotics. This review aims to guide materials selection, device design, and system integration, accelerating the transition of waveguide photoactuators from laboratory prototypes to versatile ...

Engineering of an Ancestral McbA with Enhanced Domain Mobility Extends Biocatalytic Amide Synthesis Scope

Advanced Synthesis &Catalysis, EarlyView.
We show how engineered ancestral amide bond synthetases (ABSs) together with cofactor recycling using a single polyphosphate kinase paves the way for chemoenzymatic synthesis of pharmacophores. The figure illustrates how ancestral ABS has a more flexible C‐terminal domain, which is associated with enhanced catalytic performance and expanded amine scope.
