الملخص	Flow cytometry is a laser-based technology for analyzing and sorting individual cells based on fluorescent markers. Developed by Leonard Herzenberg in the 1970s, flow cytometry enables rapid assessment of cell phenotype, drug effects on cell populations, and therapeutic cell characterization in immunology and hematology.	The Caco-2 assay is an in vitro model system using human colon carcinoma cell monolayers to screen drug intestinal permeability. Developed by Hidalgo and colleagues in 1989, Caco-2 cells differentiate into an epithelial barrier resembling intestinal mucosa, enabling rapid assessment of drug absorption potential and identification of transporter-mediated transport.	Patch-clamp electrophysiology is a technique for measuring ionic currents through ion channels in cell membranes, developed by Neher and Sakmann in 1976. It enables direct observation of single-channel and whole-cell currents at millisecond resolution, making it essential for characterizing drug effects on ion channels and cardiac safety assessment.
