Purification of Disassembled Capsid Protein by Hydroxyapatite Chromatography Enhances Virus‐Like Particle Recovery

open access: yesBiotechnology and Bioengineering, EarlyView.
ABSTRACT Virus‐like particles (VLPs) are a promising modality with extensive applications in prophylactic and therapeutic vaccine design. Human Papillomavirus (HPV) vaccines are one such example where VLP vaccine applications have led to the successful reduction in HPV‐associated diseases, such as cervical cancer.

Metal nanostructure‐coupled label‐free localized surface plasmon resonance biosensors for rapid and sensitive disease diagnosis

open access: yesBMEMat, EarlyView.
LSPR biosensing enables rapid, sensitive, and low‐sample‐volume detection of biomarkers, with broad applications in diagnosing cancer, infectious, and chronic diseases. Advances in nanostructure design, micro/nanofabrication, and microfluidic integration have expanded the potential of LSPR sensors in biomedical diagnostics.

Cross‐Dehydrogenative Coupling Reactions With Redox‐Active Guanidine Reagents

open access: yesChemistry – A European Journal, EarlyView.
ABSTRACT Cross‐dehydrogenative coupling (CDC) reactions are attractive and environmentally friendly ways to form new C‐C and other element‐element bonds. Here, we report the first CDC reactions triggered by a redox‐active guanidine reagent. N‐phenyltetrahydroisoquinoline and derivatives with electron‐donating and withdrawing substituents at the N ...

Multivalent RNA‐Cleaving Agents on a Cubic Octameric Silsesquioxane Core

open access: yesChemistry – A European Journal, EarlyView.
RNA‐cleaving agents on a cubic octameric silsesquioxane core were synthesized and characterized. Several catalytic systems of these structures were screened using hexaribonucleotide models. The best systems were then further used to study their catalytic efficiency in cleaving a HER2 mRNA model sequence. The induced cleavage sites were also determined.

The Radical Chemistry of 2,3‐Diguanidinopyridines: Coordination and Visible‐Light Photochemistry

open access: yesChemistry – A European Journal, EarlyView.
Substitution at the pyridine core of 2,3‐diguanidinopyridines was used to develop novel redox‐active molecules with three interconvertible redox states. They are applied as redox‐active ligands in coordination chemistry. Visible‐light irradiation of the pyridine N‐benzylated molecules leads to photoconversion to a higher‐energetic isomer.

C‐Terminal Functionalization Methods of Amino Acids, Peptides, and Proteins

open access: yesChemistry – A European Journal, EarlyView.
C‐terminal functionalization offers powerful routes to peptide and protein diversification, yet epimerization, hydrolysis, and selectivity remain key challenges. This Review surveys enzymatic, decarboxylative, and condensation strategies, highlighting advances toward chemo‐ and regioselective, protecting‐group‐free, atom‐efficient methods applicable to

Modular Assembly of a Biocatalytic Material for Stereoselective C─Si Bond Formation

open access: yesChemistry – A European Journal, EarlyView.
A modular, carrier‐free enzyme foam derived from Rhodothermus marinus cytochrome c combines structural stability with catalytic efficiency for stereoselective C─Si bond formation. Streptavidin (STV)‐mediated protein crosslinking creates a robust, self‐supporting materials platform for next‐generation biocatalysis.
