Chemists have been making important contributions in the exciting field of biosensors. A biosensor is a device that recognizes a target molecule in a sample and interprets its concentration as an electrical signal [...]

Recent research has shed more light on the biological and chemical consequences of exposure to cigarette smoke.
In the first study, reported in the October 1996 issue of Science (carcinogens from cigarette smoke. The P53 gene is called [...]

For several years now, chemists and biologists have been intrigued with DNA “antisense” technology. For example, chemists have designed modified RNAs which, through complementary base-pairing, can target specific regions of viral RNA. Such molecules are of interest as potential antiviral drugs. Similarly, it is possible to design oligonucleotides that are complementary to a target region [...]
