Article Abstract
Dual probe porphyrin-gold nanorod polyelectrolyte microcapsules were developed to explore the enhancing effects of a plasmonic interface of self-assembled gold nanoparticles in the fluorescence emission from porphyrins loaded into the capsules' core. An analysis of fluorescence lifetime imaging microscopy (FLIM) data reports a notable 10-10-fold increase in the maximum detected photon rates from diffraction-limited spots and an overall six-fold increase in fluorescence as averaged over the whole microcapsule area. Large emission enhancements were correlated with decreases in fluorescence lifetimes. The microcapsule's design proved effective in achieving high fluorescent hybrids and may shed light on new possibilities for advanced materials imaging applications.

Several micro- and nanoplastic particle (MNP) traits, like polymer type, size, and shape, have been shown to influence MNP toxicity. However, the direction and strength of these moderating effects are often unclear, and generalizations from single studies are challenging to establish. Meta-analyses increase generalizability and derive more accurate and precise effect size estimates by combining measurements from published studies.

Integrating surface-enhanced fluorescence (SEF) and surface-enhanced Raman spectroscopy (SERS) into a single probe is a natural step forward for plasmon-enhanced spectroscopy (PES), as SEF enables enhanced fluorescent imaging for fast screening of targets, while SERS allows ultrasensitive trace molecular characterization with specificity. However, many challenges remain, e.g.

Introduction: Obesity remains a critical global health challenge, intricately linked to poor dietary quality, gut microbiota dysbiosis, and mitochondrial dysfunction.
Purpose: This study aimed to investigate the comparative effects of brown rice, meal replacements, and thiazolidinediones on mitochondrial abundance and gut microbiota composition in a rat model of diet-induced obesity.
Methods And Materials: A total of twenty male Sprague Dawley rats were randomly assigned to five groups: control, high-fat high-fructose diet, and three intervention groups receiving the same obesogenic diet supplemented with brown rice, meal replacement, or thiazolidinediones for twelve weeks.

Parallel syntheses and their throughput capabilities are powerful tools for the rapid generation of molecule libraries, making them highly beneficial for accelerating hit identification in early-stage drug discovery. Utilizing chemical spaces and virtual libraries enhances time and cost efficiency, enabling the faster exploitation of chemically diverse compounds. In this study, a parallel synthesis method for rapidly generating a 5'-amino-5'-deoxy adenosine-based amide and sulfonamide library of 42 compounds is described with high yields and purity, which is economical and ecological due to the reduced requirements for extensive purification.

In this work, a fluorescent probe, VanPI-CarE, with a vanillin-pyridine-imidazole core structure was developed for carboxylesterase (CarE) detection in macrophage polarization during bone homeostasis. The probe responded to CarE with a distinct fluorescence reporting signal at 490 nm upon excitation at 355 nm. Tests in solution showed the advantages of VanPI-CarE, including high sensitivity, excellent stability under various working conditions, high selectivity, and low cytotoxicity.
