DNA, or deoxyribonucleic acid, is the hereditary material in humans and almost all other organisms. Nearly every cell in a person’s body has the same DNA. Most DNA is located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA or mtDNA).

Microfluidic chips advance neurodegenerative disease research

Researchers review the role of microfluidic chip models in understanding neurodegenerative diseases, offering insights into the disease mechanisms and potential for drug development through innovative lab-on-a-chip technologies.
