Bacteriophages and their structural organisation [PDF]

, 2012
Viruses are extremely small infectious particles that are not visible in a light microscope, and are able to pass through fine porcelain filters. They exist in a huge variety of forms and infect practically all living systems: animals, plants ...

Plant‐Produced Viral Nanoparticles Decorated with Nanobodies Against HER2 Improve Retention and Recruitment of Immune Cells in Solid Tumors

Advanced Healthcare Materials, EarlyView.
Potato virus X is a filamentous RNA plant virus that can be engineered into a molecular tool for cancer therapy. We produced genetically‐encoded virus‐derived nanoparticles decorated with nanobodies targeting cancer cell receptors, epidermal growth factor receptor (EGFR) and human epidermal growth factor 2 (HER2).

Bacteria‐Responsive Nanostructured Drug Delivery Systems for Targeted Antimicrobial Therapy

Advanced Materials, EarlyView.
Bacteria‐responsive nanocarriers are designed to release antimicrobials only in the presence of infection‐specific cues. This selective activation ensures drug release precisely at the site of infection, avoiding premature or indiscriminate release, and enhancing efficacy.

Peptidoglycan Remodeling Enables Escherichia coli To Survive Severe Outer Membrane Assembly Defect

mBio, 2019
Gram-negative bacteria have a tripartite cell envelope with the cytoplasmic membrane (CM), a stress-bearing peptidoglycan (PG) layer, and the asymmetric outer membrane (OM) containing lipopolysaccharide (LPS) in the outer leaflet.

Soft Ionic and Electronic Triboelectric Nanogenerators: Toward Attachable and Implantable Biomedical Applications

Advanced Materials, EarlyView.
This review provides an overview of triboelectric nanogenerator (TENG)–based biomedical applications by classifying studies into electronic and ionic systems across attachable and implantable platforms. It summarizes key material choices, device structures, and working mechanisms that characterize current TENG‐based research, and outlines six future ...

Membrane Protein Simulations: Ion Channels And Bacterial Outer Membrane Proteins

, 2003
Publisher Summary The chapter focuses on two classes that have been investigated by a number of research groups—namely, ion channels and bacterial outer membrane proteins—rather than attempt to cover all simulations of membrane proteins. Ion channels play a key role in the electrical activity of cells of the nervous system. However, channels are also

Two‐Photon 3D Printing of Functional Microstructures Inside Living Cells

Advanced Materials, EarlyView.
This study demonstrates 3D printing inside living cells by using two‐photon photo‐lithography. A bio‐compatible photoresist is injected into cells and selectively polymerized with a femtosecond laser, creating custom‐shaped intracellular structures with submicron resolution.

Bioengineering bacterial outer membrane vesicles as vaccine platform.

Biotechnology Advances, 2017
Outer membrane vesicles (OMVs) are naturally non-replicating, highly immunogenic spherical nanoparticles derived from Gram-negative bacteria. OMVs from pathogenic bacteria have been successfully used as vaccines against bacterial meningitis and sepsis ...

NIR‐Activated Ag2S Quantum Dots for Efficient Broad‐Spectrum Antibacterial and Biofilm Disruption

Advanced Materials Interfaces, EarlyView.
This study presents a novel non‐antibiotic strategy leveraging NIR‐activated Ag2S QDs for synergistic PTT/PDT. The platform degrades the protective extracellular matrix via localized hyperthermia, facilitating deep penetration and ROS‐induced oxidative damage.

Structural insights into the secretin complex of a type IVb pilus system

Nature Communications
The bundle-forming pilus (BFP) system in enteropathogenic Escherichia coli (EPEC) produces type IVb pili that enable bacterial auto-aggregation, facilitating bacterial adhesion, colonization, and virulence.
