研究目的: |
(1)构建基于3D DNA CRISPR纳米机器的便携式传感平台,实现对肺癌ctDNA EGFR(L858R)突变型与野生型的高特异性、超灵敏识别,突破传统检测方法在低丰度ctDNA检测中的局限性; (2)系统评估所构建传感平台在健康个体及肺癌不同发展阶段患者血浆、血清样本中的检测性能,明确其在复杂生物基质中的稳定性、重复性及检测限,为临床转化提供技术依据; (3)通过与临床“金标准”PCR技术的检测结果进行比对,验证该传感平台的临床有效性与可靠性,并建立血液中ctDNA EGFR(L858R)相关检测参数与肺癌患者病情进展、预后的关联,为肺癌精准筛查、疗效评估及个性化治疗方案制定提供新的技术支撑。 |
||||||||||||||||||||||
|
Objectives of Study: |
1.Construct a portable sensing platform based on 3D DNA CRISPR nanomachines to achieve highly specific and ultrasensitive discrimination between mutant-type (L858R) and wild-type EGFR ctDNA in lung cancer, overcoming the limitations of traditional detection methods for low-abundance ctDNA; 2. Systematically evaluate the performance of the developed sensing platform using plasma and serum samples from healthy individuals and lung cancer patients at different disease stages, clarifying its stability, reproducibility, and limit of detection in complex biological matrices, thereby providing a technical basis for clinical translation; 3. Validate the clinical effectiveness and reliability of the sensing platform by comparison with the clinical "gold standard" PCR technique, and establish correlations between ctDNA EGFR (L858R) detection parameters in blood and disease progression/prognosis of lung cancer patients, offering new technical support for precision screening, therapeutic response assessment, and personalized treatment planning in lung cancer. |
