暗场显微镜下的纳米颗粒识别与观测细胞膜上的扩散运动
Identification of Nanoparticles and Observation of Diffusion on Cell Membranes Using Darkfield Microscopy:Recommending a Chemical Measurement Experiment
摘要
Abstract
Single-particle tracking represents a significant technological breakthrough for real-time observation of dynamic biological processes,particularly in uncovering mechanisms hidden in static observations.With advancements in optical microscopy,commercial instruments now enable real-time observation of biological processes at the microscopic scale.This experiment explores the size effect of plasmonic nanomaterials using gold and silver nanoparticles as imaging probes.Additionally,live cell imaging experiments are designed to introduce single-particle tracking into undergraduate education by observing the diffusion of gold nanorods on cell membranes as an exemplary experiment in Chemical Metrology and Technology.The experiment is rich in content and engaging,targeting second-and third-year undergraduates who have a foundational understanding of chemistry and chemical biology and are interested in Chemical Metrology and Technology.The goal is to integrate cutting-edge research in single-particle tracking into undergraduate teaching,encouraging independent exploration and stimulating students'interest in scientific research while cultivating their professional skills.关键词
