Single-cell analysis is a rapidly growing field in biology and biotechnology that focuses on studying and analyzing individual cells rather than bulk populations of cells. This approach allows researchers to examine the heterogeneity and diversity of individual cells within a population, which can provide important insights into cellular behavior, function, and response to stimuli. Single-cell analysis techniques include flow cytometry, single-cell RNA sequencing, and single-cell imaging, among others. This research area has broad applications in fields such as cancer research, immunology, developmental biology, and regenerative medicine.
