Advanced Materials Technologies, EarlyView.A label‐free impedimetric biosensor based on electroactive 3D porous graphene foam enables ultrasensitive and selective detection of CD81 protein and MCF‐7 cell‐derived extracellular vesicles in human serum. Detection limits of 0.048 fg/mL for CD81 and ∼24 EVs/mL are achieved, demonstrating a robust platform for selective, label‐free, and ...

3D‐Printed Corneal Substitutes: Materials, Fabrication, and Preclinical Progress
Advanced Materials Technologies, EarlyView.Successful clinical translation of 3D‐printed corneal substitutes relies on the interplay between the bioink properties, cellular component, and the fabrication process. These factors influence the critical properties of the construct, including optical transparency, mechanical stability, suture retention, that ultimately govern long‐term stromal ...

Information Transmission Strategies for Self‐Organized Robotic Aggregation
Advanced Robotics Research, EarlyView.In this review, we discuss how information transmission influences the neighbor‐based self‐organized aggregation of swarm robots. We focus specifically on local interactions regarding information transfer and categorize previous studies based on the functions of the information exchanged.

Type VI secretion system baseplate
Nature Microbiology, 2018Bacteria employ a specialized weapon known as the type VI secretion system to defend themselves from competing organisms. A new study reveals the molecular architecture of the type VI secretion system and highlights conserved mechanistic similarities with contractile phage tails.

Bacterial Defense against the Type VI Secretion System
Trends in Microbiology, 2021Bacteria have evolved systems dedicated to interbacterial competition. Here we highlight defenses utilized by Gram-negative cells against type VI secretion system (T6SS)-wielding competitors, including physical barriers, genetically encoded antidotes, and stress responses.

Bacterial strategies for immune systems — Role of the type VI secretion system
International Immunopharmacology, 2023The process of host infection by bacteria is complicated. Bacterial infections strongly induce the host immune system, which necessitates a robust clearance of the infection. However, bacteria have over time developed strategies that enable their evasion of attacks by the host immune system.
