Article Abstract
Herein, we present a pioneering approach to enhancing Förster resonance energy transfer (FRET) efficiency through the synergistic integration of cetyltrimethylammonium bromide (CTAB) surfactants and ZnS quantum dots (QDs) within a zinc quinolate complex (ZQC)-dye (Rhodamine B: RhB) system. FRET efficiency is elevated from 13.1% to 49% with surfactants alone and further to an impressive 93.6% with the addition of QDs. This advancement highlights the vital role of chemical environment modifications in regulating energy transfer mechanisms. Employing nuclear magnetic resonance (NMR) and Fourier-transform infrared (FTIR) spectroscopy alongside density functional theory (DFT) calculations, the study provides comprehensive insights into molecular interactions, electronic behavior, and structural transformations driving enhanced energy transfer. The findings set a benchmark for high-performance FRET systems, offering a robust platform for applications in bioimaging, biosensors, optoelectronics, and nanophotonics. By blending experimental innovation with theoretical validation, this work paves the way for transformative advancements in optical- and nanomaterial-based technologies.

Staphylococcus aureus is ranked among the top five most common foodborne pathogens affecting public health and the economy worldwide. To improve detection and reduce diagnostic burdens, several detection methods from traditional culture-based techniques to biosensing platforms have evolved. Among several markers, surface proteins are considered to be the most important markers due to the specific roles they play in the survival and colonization of the bacterium on hosts.

The emission-based fluorescence resonance energy transfer (E-FRET), renowned for its rapid detection, noninvasiveness towards fluorophores, and compatibility with both wide-field and confocal microscopy, is extensively employed in dynamically monitoring intermolecular interactions within living cells. However, E-FRET requires manual screening of hundreds to thousands of images for regions meeting specific criteria, a labor-intensive process devoid of mature automation solutions. In this article, we introduce AutoFRET, the automated and efficient solution tailored for E-FRET experimentation.

Covalent modification of proteins with ubiquitin is a critical event in TPD, yet the analytical tools for quantifying the ubiquitination kinetics have been limited. Here, we present a real-time, high-throughput fluorescent assay utilizing purified, FRET-active E2-Ub conjugates to monitor ubiquitin transfer.
