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.

Natural Design of a Stabilized Cross‐β Fold: Structure of the FuA FapC from Pseudomonas Sp. UK4 Reveals a Critical Role for Stacking of Imperfect Repeats

open access: yesAdvanced Materials, EarlyView.
We report a 3.2 Å cryoEM structure of functional amyloid protein FapC from Pseudomonas sp. UK4, an essential component of bacterial biofilm, which reveals a Greek key‐shaped protofilament, supports bioinformatically determined motifs, nuances AlphaFold predictions, emphasizes heterogeneous cross‐β stacking in amyloid cross‐seeding and shows strain ...

An Injection‐Molded Modified Silicone Rubber for Cancer‐on‐Chip Applications

open access: yesAdvanced Materials Technologies, Volume 10, Issue 6, March 18, 2025.
This study describes the characterization and application of an injection‐molded functionalized PDMS fluidic insert for the commercially available Micronit system. Modified PDMS can accommodate cell culture and is able to covalently bind proteins for long‐lasting coatings under flow‐conditions.

Transcript Identification Using Arrayed Hydrogels With TrapFISH

open access: yesAdvanced Materials Technologies, EarlyView.
TrapFISH is a novel method for high‐throughput single‐cell transcriptomics. It embeds cells in hyaluronic acid hydrogel beads and uses probe hybridization to quantify custom gene panels. By arraying hydrogels in microfluidic devices, cell barcoding is removed, enhancing scalability for studying cellular heterogeneity and rare cell states by targeting ...

Immune Checkpoint PD‐L1 Modulates Retinal Microglial Activation to Alleviate Vascular Leakage in Choroidal Neovascularization via ERK

open access: yesAdvanced Science, EarlyView.
PD‐L1 limits neuroinflammation in neovascular AMD by modulating microglial activation. Its deficiency exacerbates vascular leakage and choroidal neovascularization (CNV) via ERK signaling, while enhancing PD‐L1 reduces inflammation and neovascularization. Targeting PD‐L1 may offer a novel immunomodulatory strategy for NVAMD.

Hydrophobin‐Coated Echogenic Microbubbles for Molecular Targeting of Tumor Cells

open access: yesAdvanced Science, Volume 12, Issue 22, June 12, 2025.
Echogenic microbubbles based on hydrophobin and corresponding fusion protein (HFBI‐domZ) are developed as contrast agents for cancer diagnostics. Hydrophobin provides high stabilization of encapsulated perfluoro‐n‐butane, and fusion proteins allow further versatile functionalization with antibodies. In‐vitro experiments indicate that these microbubbles
