ADVANCE/The world's smallest pump may someday be part of drug delivery system implanted in the body; Prototype smaller than finger tip.probably the world's smallest reversible reversible, adj capable of going through a series of changes in either direction, forward or backward (e.g., reversible chemical reaction). reversible hydrocolloid, n See hydrocolloid, reversible. pump - it's slightly smaller than the tip of a finger - may someday some·day adv. At an indefinite time in the future. Usage Note: The adverbs someday and sometime express future time indefinitely: We'll succeed someday. Come sometime. become part of a drug delivery system that can be implanted im·plant v. im·plant·ed, im·plant·ing, im·plants v.tr. 1. To set in firmly, as into the ground: implant fence posts. 2. in the body, according to according to prep. 1. As stated or indicated by; on the authority of: according to historians. 2. In keeping with: according to instructions. 3. "The Sciences." A prototype of the micro pump was developed by physicist Roland Zengerle of Germany's Institute for Micromachining and Information Technology. It moves less than one-thousandth of a drop of liquid in one cycle (actually between 10 to 30 nanoliters; a drop of water is 30,000 nanoliters). "In spite of it's size," notes the November/December issue of the magazine, "the pump is no toy. Appropriately connected to external plumbing, the micropump could serve as a highly precise way of drawing chemicals into labware for analysis, of delivering lubricants lubricants preparations for the lubrication of passages to reduce frictional injury, e.g. oily preparations, including petroleum jelly, lanolin or water-soluble preparations such as methyl cellulose. to engine parts and of pumping ink through a fountain pen. In medicine such a pump might someday part of an implantable drug delivery system." (End of ADVANCE for Monday, October 30) CONTACT: Greene Inc. Howard Greene, 516/825-0400 home: 516/374-4230 |
