BIOSENSORS ADVANCED BIOREPORTER TECHNOLOGIES FOR TARGETED SENSING OF CHEMICAL AND BIOLOGICAL AGENTS Steven Ripp and Gary S. Sayler Introduction Bioreporters refer to intact‚ living microbial cells that have been genetically engineered to produce a measurable signal in response to a specific chemical or physical agent in their environment (Figure 1). Bioreporters contain two essential genetic elements‚ a promoter gene and a reporter gene. The promoter gene is turned on (transcribed) when the

Introduction: Gas Chromatography is a technique widely used to separate complex mixtures of substances. Compounds present in a volatile liquid or gaseous solute are isolated after traveling through a coated column based on the substance’s size and intermolecular interactions. If a compound tends to bind to the column through intermolecular interactions‚ it takes a longer time to emerge compared with a compound that does not tend to stick onto the column. The level of binding experienced between the substances
Premium Chromatography Gas chromatography
The purpose of column chromatography is to separate one compound from another by the differing polarities in the compound. This technique is important in organic chemistry because certain experiments may require the separation of compounds in solution to be used for chemical synthesis and/or analysis of a particular desired product by isolating it. Fluorene is to be separated from 9-fluorenone using the technique of column chromatography. The success of separation and purity is determined with analyzation

Key Compounds in Garlic Although garlic has been traditionally used for over 5‚000 years‚ most scientific significance has just been developed in the past 50 years. The key compounds in garlic and its preparations include the following phytochemicals. Sulfur-containing compounds Recently‚ researchers have been focusing on the benefits of a variety of sulfur-containing compounds in garlic instead of allicin. These are classified as oil- and water-soluble compounds. Oil-soluble compounds include
