... properties, and reactions of matter (especially of atomic and molecular systems). For years chemistry has been divided into four "classical" areas: analytical, inorganic, organic, and physical. Chemistry has played a major role in pharmaceutical advances, forensic science, and modern agriculture. Organic chemistry is essential in biological and medical fields. All living organisms are composed of abundances ... of the analytical chemical information play important roles in selecting the appropriate chemical analysis technique.

To some extent, we used biology in the 1990s, and will for the next century, the way we used chemistry in the 1950s and 1960s. Many of the new products and services that we are developing replace what was done by chemical methods, 30 to 40 years ago. Most of ... . Now 10 to 15 biotech products are approved each year. Biotechnology is a very powerful technology, and will continue to be used to replace chemical approaches. In the 1950s and 1960s, chemistry was seen as being the great technology wonder and wa...

... poisons. Instead of cleaving DNA, the enediyne cleaves the protein and thereby inactivates itself6. The cell is preserved. Scientists have long known that bacteria can hinder antibiotics by rearranging their chemistry to keep a drug from binding to a cell. This new antibiotic resistance mechanism does not bode well for the fight against dangerous and sometimes deadly bacteria (i.e. flesh-eating bacteria). It clearly ... ...
