Abstract
Monitoring Rocuronium Bromide (RcBr), a neuromuscular blocker widely used in anesthesia, is clinically important yet analytically underexplored. We report a fluorescence-based sensor for RcBr using Thioflavin-T (ThT) aggregates templated by γ-sulfated cyclodextrin (γ-SCD). This competitive displacement assay exploits the high binding affinity of Rocuronium for γ-SCD to displace Thioflavin-T from supramolecular aggregates, resulting in a fluorescence turn-off response. The sensor exhibits submicromolar sensitivity (LOD ∼ 0.2 ± 0.02 μM), rapid response (<1 min), and high selectivity over biological interferents. Its functionality in diluted human serum demonstrates potential for possible clinical applications. This work presents a novel optical approach for RcBr sensing that may support future developments in neuromuscular blockade monitoring.
期刊介绍：
ACS Applied Bio Materials is an interdisciplinary journal publishing original research covering all aspects of biomaterials and biointerfaces including and beyond the traditional biosensing, biomedical and therapeutic applications.
The journal is devoted to reports of new and original experimental and theoretical research of an applied nature that integrates knowledge in the areas of materials, engineering, physics, bioscience, and chemistry into important bio applications. The journal is specifically interested in work that addresses the relationship between structure and function and assesses the stability and degradation of materials under relevant environmental and biological conditions.
