研究目的:

本研究旨在针对临床对映体检测中现有技术效率低、灵敏度不足、抗干扰能力弱及适配性差的核心问题,结合手性诱导自旋选择性(CISS)效应与等离子体共振效应的协同优势,开展自旋极化可调的手性等离子体薄膜的开发及临床应用研究,具体研究目的如下: 1. 开发自旋极化可调的手性等离子体薄膜,优化其制备工艺,实现自旋极化特性的动态调控,使其适配临床不同类型生物样本(血清、尿液)、不同浓度对映体的检测需求,确保薄膜具备结构稳定、检测速度快、样品用量少的临床应用优势,满足临床批量检测、快速诊断的实际需求。 2. 验证该双模式识别体系在临床生物样本(血清、尿液)中对映体识别与区分的可行性、可靠性及安全性,明确其检测性能(如灵敏度、特异性、重复性),为其临床转化应用提供科学依据。  

Objectives of Study:

This study aims to address the critical limitations of current enantiomer detection technologies in clinical settings, including low efficiency, insufficient sensitivity, weak anti-interference capacity, and poor adaptability. By integrating the synergistic advantages of the chiral-induced spin selectivity (CISS) effect and plasmonic resonance effect, we develop spin-polarization-tunable chiral plasmonic films and investigate their clinical applications. The specific research objectives are as follows: 1.To develop spin-polarization-tunable chiral plasmonic films, optimize their fabrication processes, and achieve dynamic regulation of spin-polarization properties. This will enable adaptation to the detection requirements of enantiomers with diverse concentrations in various clinical biological samples (serum and urine). The films will be endowed with clinically favorable features including structural stability, rapid detection, and low sample consumption, to meet the practical demands of high-throughput clinical testing and rapid diagnosis. 2.To verify the feasibility, reliability, and safety of the dual-mode recognition system for enantiomer identification and discrimination in clinical biological samples (serum and urine), and systematically characterize its detection performance (e.g., sensitivity, specificity, and repeatability), thereby providing a scientific basis for its clinical translation and application.
