Automated Label‐Free Assay for Viral Detection and Inhibitor Screening via Biomembrane‐Functionalized Microelectrode Arrays

open access: yesAdvanced Materials, EarlyView.
A bioelectronic sensor integrating 2D cell membranes with organic microelectrode arrays enables detection of SARS‐CoV‐2 fusion pathways. Natively‐expressed viral receptors promote monitoring of viral entry and screening of antibody‐based inhibitors.

The role of cellular adhesion molecules in virus attachment and entry [PDF]

open access: yes, 2015
As obligate intracellular parasites, viruses must traverse the host-cell plasma membrane to initiate infection. This presents a formidable barrier, which they have evolved diverse strategies to overcome.

Kelvin Probe Force Microscopy in Bionanotechnology: Current Advances and Future Perspectives

open access: yesAdvanced Materials, EarlyView.
Kelvin probe force microscopy (KPFM) enables the nanoscale mapping of electrostatic surface potentials. While widely applied in materials science, its use in biological systems remains emerging. This review presents recent advances in KPFM applied to biological samples and provides a critical perspective on current limitations and future directions for

Single-channel measurements of an N-acetylneuraminic acid-inducible outer membrane channel in Escherichia coli [PDF]

open access: yes, 2012
NanC is an Escherichia coli outer membrane protein involved in sialic acid (Neu5Ac, i.e., N-acetylneuraminic acid) uptake. Expression of the NanC gene is induced and controlled by Neu5Ac. The transport mechanism of Neu5Ac is not known.

An Anti‐Myd88 Peptide Synergistically Enhances the Anti‐Inflammatory Effects of Extracellular Vesicles from Naïve Umbilical Cord MSC or HEK293F CD24 Overexpressing Cells

open access: yesAdvanced Materials Interfaces, EarlyView.
This study confirms that extracellular vesicles (EVs) derived from mesenchymal stem cells (MSCs) or HEK293F cells overexpressing CD24 have anti‐inflammatory effects in macrophages and monocytes. Further loading either of these EVs with an anti‐Myd88 peptide synergistically enhanced the anti‐inflammatory effects of the EVs.

Prediction of specific virus outbreaks made from the increased concentration of a new class of virus genomic peptides, replikins. [PDF]

open access: yes, 2011
Advance warning of pathogen outbreaks has not been possible heretofore. A new class of genomic peptides associated with rapid replication was discovered and named replikins. Software was designed to analyze replikins quantitatively.

Development of Sialic Acid-coated Nanoparticles for Targeting Cancer and Efficient Evasion of the Immune System

open access: yesTheranostics, 2017
Evading the reticuloendothelial system (RES) remains a critical challenge in the development of efficient delivery and diagnostic systems for cancer. Sialic acid (N-acetylneuraminic acid, Neu5Ac) is recognized as a “self” marker by major serum protein ...

Assay System Based on Metabolic Glycoengineering‐Enabled Click Chemistry for the Efficient Evaluation of Complement‐Regulatory Peptide Coatings on Endothelial Cells

open access: yesAdvanced Materials Interfaces, EarlyView.
Metabolic glycoengineering combined with click chemistry efficiently immobilizes clickable factor H (FH)‐binding peptides onto endothelial cell surfaces, creating stable, uniform coatings that recruit FH and enhance resistance to complement‐mediated inflammation.
