Engineering Bacterial Secretion Systems for Enhanced Tumor Imaging and Surgical Guidance

open access: yesAdvanced Materials, EarlyView.
This study presents a novel contrast agent platform, Streptavidin Associated Salmonella (SAS), for fluorescence image guided surgery. SAS selectively colonizes tumors and secretes streptavidin, enabling precise delineation of invasive tumor margins with prolonged signal retention.

Bioinspired Smart Nanogels for Rapid Blue Laser‐Activated Hemostasis in Gastrointestinal Bleeding

open access: yesAdvanced Materials, EarlyView.
Waxberry‐inspired branched‐silica nanogel can swiftly stop bleeding upon blue laser endoscopy for gastrointestinal hemostasis in the esophagus, stomach, and duodenum of mini‐pigs. Abstract Gastrointestinal bleeding (GIB) is a critical condition that requires rapid and effective intervention.

Fabrication of Schiff Base Interfacial Films via Polyethyleneimine and Glutaraldehyde for pH‐Responsive Oil‐in‐Water High Internal Phase Emulsions

open access: yesAdvanced Materials Interfaces, EarlyView.
Due to the Schiff base reaction between polyethyleneimine and glutaraldehyde in the aqueous phase, a pH‐responsive interfacial film is constructed at the interface of the two immiscible phases. Consequently, both pH‐reversible high internal phase emulsions and pH‐controlled release capsules can be easily fabricated using this emulsion system.
