The DNA double helix was first elucidated by J.D. Watson and F.H.C. Crick over a half century ago. However, no one could actually “see” the well-known structure ever. Among all real-space observation ...

Label-free electrical detection of DNA hybridization has been achieved by employing Au/SiO/sub 2//Si MOS diodes and poly-Si TFTs. The detection is based on the modulation of the gate voltage ...

Coumarin derivatives have found application as probes for the hydroxyl radical because one of the products of the reaction between them is a highly fluorescent umbelliferone. We have examined the ...
