A Sensitive Fluorescent Assay for Tetracycline Detection Based on Triple-helix Aptamer Probe and Cyclodextrin Supramolecular Inclusion

Hui He et al.

Summary: An effective pyrene excimer signaled fluorescent biosensor for the determination of tetracycline was developed based on triple-helix aptamer probe (TAP) and supramolecular inclusion of cyclodextrin. The biosensor showed high sensitivity and specificity in detecting the target molecule, offering a simple and cost-effective protocol.

Sudabe Mandani et al.

Summary: A pH-sensitive quantum dots gatekeeper drug delivery system using MSNs and MPA-ZnS QDs as GEN carriers and nanopore sealers was proposed, allowing controlled drug release under different pH conditions. The system showed good biocompatibility and antibacterial effects, with drug release rate being controlled by pH-dependent pore sealing and opening mechanisms.

Rapid optical sensor for recognition of explosive 2,4,6-TNP traces in water through fluorescent ZnSe quantum dots

Vineet Sharma et al.

Summary: Blue fluorescent zinc selenide quantum dots were synthesized using 3-mercaptopropionic acid at a lower temperature through a direct aqueous route. The photoluminescence characteristics were utilized to detect picric acid in water, with a selective quenching effect observed with increasing concentrations. The proposed sensing probe showed linearity in the range of 2.0 μM-0.25 mM with a detection limit of 12.4 x 10(-6) M, without interference from other nitroaromatic compounds.

Study of the interaction mechanism between hydrophilic thiol capped gold nanoparticles and melamine in aqueous medium

Sara Cerra et al.

Summary: Efforts have been made to obtain colloidal-based systems capable of detecting melamine in food samples. This study reported the recognition of melamine in aqueous solution using gold nanoparticles, with melamine-induced aggregation of AuNPs as the sensing method successfully detecting melamine in the range of 2.5-500 ppm. The negatively charged AuNPs3MPS are potentially useful for determining melamine contents in aqueous solution.
