Bioxolography Using Diphenyliodonium Chloride and N‐Vinylpyrrolidone Enables Rapid High‐Resolution Volumetric 3D Printing of Spatially Encoded Living Matter

open access: yesAdvanced Materials, EarlyView.
Bioxolography, a novel volumetric 3D‐bioprinting technique, enables rapid and high‐resolution fabrication of >1 cm3 engineered living materials. A newly developed three‐component photoinitiator system significantly enhances the photoreactivity of gelatin methacryloyl‐based bioresins, allowing for precise xolographic bioprinting.

Harnessing Synergistic Cooperation of Neighboring Active Motifs in Heterogeneous Catalysts for Enhanced Catalytic Performance

open access: yesAdvanced Materials, EarlyView.
This review examines the critical role of neighboring active motifs in heterogeneous catalysts, emphasizing how their synergistic cooperativity can be rationally designed to modulate catalytic properties. The discussion centers on the modulation of electronic and geometric structures, categorizing the catalytic systems into metal‐acid (Brønsted/Lewis ...

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.

Well‐Defined Poly(HPMAm) Brushes via Surface‐Initiated RAFT Polymerization; A Mixed‐Chain Transfer Agent (CTA) Approach

open access: yesAdvanced Materials Interfaces, EarlyView.
A simple method relying on surface‐initiated RAFT polymerization is presented using a mixed‐chain transfer agent (mixed‐CTA) approach to grow well‐defined poly(HPMAm) brushes with precise control, achieving >70 nm thickness in 4 h at moderate temperature, 50 °C. Abstract Over three decades, efforts to prevent non‐specific protein adsorption on surfaces

Colorimetric Sensors with Enhanced Sensitivity and Angle‐independence

open access: yesAdvanced Sensor Research, EarlyView.
This review discusses various approaches, including the use of photonic crystals and colloidal photonic crystals as structural materials, and surface plasmon resonance as a light manipulation mechanism, to improve the sensitivity of colorimetric sensors.
