Single-cell metabolomic analysis

Definition

Single-cell metabolomic analysis is the study of the metabolites present in individual cells to understand their metabolic state and heterogeneity. This approach allows researchers to investigate variations in cellular metabolism that can provide insights into disease mechanisms, cellular responses, and the functionality of specific cell types. By focusing on single cells rather than bulk populations, this technique enhances the detection of metabolic differences that might be masked in larger samples.
