AI Article Synopsis

  • Researchers developed "turn-on" FRET-based luminescent probes using iridium(III) complexes to detect the amino acids cysteine (Cys) and homocysteine (Hcy).
  • The study focused on how the size of the probe affects the brightness of the emitted light when detecting these amino acids.
  • Findings suggest a link between the probe's steric bulk and the enhancement of emission intensity, aiding in the effective detection of Cys and Hcy.

Article Abstract

"Turn-on" FRET-based luminescent probes containing iridium(III) complexes for the detection of Cys and Hcy have been designed and synthesized. The relationship between the steric bulk of the probe and the corresponding emission intensity enhancement towards detection of Cys and Hcy has been studied.

Decorating a gold surface with molecular-level control over the positioning of DNA probes was demonstrated using a self-assembled monolayer (SAM) of wireframe DNA nanocube structures. The DNA nanocubes were specifically adsorbed and oriented using thiol-modified DNA on one face of the cube. The DNA nanocube SAM had a uniform coverage over the gold single crystal bead electrode with a separation of 20-30 nm measured by AFM.

Environmental monitoring and the detection of antibiotic contaminants require expensive and time-consuming techniques. To overcome these challenges, gold nanoparticle-mediated fluorometric "turn-on" detection of Polymyxin B (PMB) in an aqueous medium was undertaken. The molecular weight of polyethyleneimine (PEI)-dependent physicochemical tuning of gold nanoparticles (PEI@AuNPs) was achieved and employed for the same.

We designed a highly sensitive fluorescent sensor for the early detection of sarcosine, a potential biomarker for prostate cancer. This sensor was based on surface-cobalt-doped fluorescent carbon quantum dots (Co-CD) using a FRET-based photoluminescent sensing platform. Blue luminescent carbon quantum dots (CQD) were synthesised through a hydrothermal approach, utilizing tree pod shells.
