Review of Gastrointestinal Capsule Robots: Materials, Actuation, Diagnostics, and Therapeutics

Advanced Science, EarlyView.
This review examines gastrointestinal capsule robots through a systems engineering lens, covering shell materials, actuation and localization strategies, diagnostic modalities, therapeutic interventions, and commercialization status. By mapping the complete technological chain from fabrication to clinical deployment, this work identifies critical gaps ...

Visible‐Light‐Mediated Lewis Acid‐Catalyzed Diradical Hydrogen Atom Transfer Reaction of Enamides

Advanced Science, EarlyView.
The Lewis acid catalysis was crucial for the success of the DHAT reaction of enamides by lowering the energy of the triplet excited state and modulating the reactivity of the formed diradical intermediate in a carbon‐to‐carbon 1,5‐DHAT and consequent cyclization that allows the functionalization of C(sp3)−H bonds to construct a variety of novel β ...

Overcoming Transmission Barriers: A Dual‐Functional Adhesive Hydrogel for Direct Monkeypox Virus Neutralization and Wound Healing

Advanced Science, EarlyView.
MPXV infection leads to persistent viral replication and severe local inflammation, while existing treatments cannot simultaneously remove viruses and repair injured tissue. This study constructs Polymer@mPDA@Gel hydrogel via a two‐step hierarchical assembly method: mPDA anchors photothermal polymers to form antiviral photothermal subunits, which are ...

Heat‐Suppressing Projection Two‐Photon Lithography Enables High‐Throughput Sub‐Micrometer Manufacturing of Biopolymer Hydrogels for Tissue Engineering

Advanced Science, EarlyView.
The iLEAP technique integrates high‐throughput two‐photon lithography with extrusion printing, bridging sub‐micrometer precision and macroscopic scaffold fabrication. By employing a low‐exothermic photoinitiator, it mitigates thermal damage to biopolymers and preserves bioactivity.

Natural Antimicrobial Compounds as Promising Preservatives: A Look at an Old Problem from New Perspectives

Molecules
Antimicrobial compounds of natural origin are of interest because of the large number of reports regarding the harmfulness of food preservatives. These natural products can be derived from plants, animal sources, microorganisms, algae, or mushrooms.

Modification‐Selective Inhibition of Succinate Dehydrogenase a Enables Tumor‐Restricted Mitochondrial Modulation

Advanced Science, EarlyView.
This work identifies acetylation‐dependent SDHA homeostasis as a determinant of tumor‐specific metabolic vulnerability. Guided by this mechanism, a modification‐selective inhibitor, ZPI‐3, selectively targets non‐acetylated SDHA, achieving tumor‐restricted SDH inhibition and effective bladder cancer control. Differential responses in clinical specimens

Light-Activable Silver Nanoparticles for Combatting Antibiotic-Resistant Bacteria and Biofilms

Molecules
Silver nanoparticles (AgNPs) are among the most widely used nanoparticulate materials for antimicrobial applications. The innate antibacterial properties of AgNPs are closely associated with the release of silver ions (Ag+) and the generation of reactive

RNA Promotes Synapsin Condensates That Organize Synaptic Vesicles in Live Neurons and Enable Localized Translation in Reconstituted System

Advanced Science, EarlyView.
Condensates at synapses organize synaptic vesicles (SVs) and are crucial for efficient neurotransmitter release, yet how RNA contributes to this mesoscale architecture remains poorly understood. Here we uncover that RNA modulates synapsin–driven condensates.

Rapid Photogelation of Low‐Concentration Polymer Solutions via Photodimerization of o‐Ethylnitrobenzene

Advanced Science, EarlyView.
Upon UV irradiation, flexible and tough hydrogels are formed rapidly (>0.5 s) from dilute (>0.5 wt%) solutions of o‐ethylnitrobenzene–modified PVA. At ∼1.5 wt%, the hydrogels withstand up to 10 MPa compression, remain handleable even after 200‐fold swelling.
