Research Topic: Magnetic microbeads can be manipulated
and steered by external magnetic fields and allow
stretching and overwinding experiments with single (DNA) molecules at a sensitivity
level downto 0,001 pN. With our magnetic tweezers (MT) apparatus
(PicoTwist, Lyon - France) we investigate and quantify the binding of proteins, fluorescent dyes and chemotherapeutic agents to DNA. |
