A Comprehensive Study of Quantum Dots: Ranging From Synthesis to Applications in Electrochemical Biosensors in the Detection of Biomolecules, Gastrointestinal Diseases, and Electrophysiology

open access: yesNano Select, EarlyView.
Quantum dots (QDs) typically refer to extremely small semiconductor particles, often no larger than 10 nm. The development of efficient biosensors for the sensitive and selective detection of biomolecules is essential for fundamental research in analytical chemistry, biomedicine, clinical diagnosis, and electrophysiology.

Spectroscopic, X‐Ray Crystallographic, and Hirshfeld Surface Analyses for the Investigation of Intermolecular Interactions in Carboxamide Hydrazone Hybrids

open access: yesChemistryOpen, EarlyView.
Two novel carboxamide hydrazone hybrids are synthesized and characterized. Structural, spectroscopic, and computational analyses reveal dominant hydrogen bonding, π–π stacking, and reactive sites. Compound 2b exhibits potent antibacterial activity against Staphylococcus aureus, highlighting its potential as a cost‐effective therapeutic agent.
