Fractionating DNA—from hours to minutes

Researchers of the University of Twente in The Netherlands developed a glass microchip for ultrafast separation and purification of DNA fragments. The chip, moreover, is easy to produce and cheap. The UT scientists published ...

DNA chip offers big possibilities in cell studies

A UT Dallas physicist has developed a novel technology that not only sheds light on basic cell biology, but also could aid in the development of more effective cancer treatments or early diagnosis of disease.

DNA dominos on a chip

Normally, individual molecules of genetic material repel each other. However, when space is limited DNA molecules must be packed together more tightly. This case arises in sperm, cell nuclei and the protein shells of viruses. ...

Technique to measure volumes of key 'Lab on a Chip' components

Imagine shrinking tubes and beakers—in fact, most of a clinical chemistry lab—down to the size of a credit card. When engineers figured out how to do that two decades ago, they enabled complex tests to be performed with ...

Nanopores light up for reading out DNA

Nanopores are ideally suited for threading DNA molecules through them, enabling the genetic code to be read out. Researchers from TU Delft want to make this technology even more powerful by equipping the pores with 'plasmonics'. ...
