Spectra Science Corp. of Providence, R.I., and Glaxo Wellcome Inc. of Research Triangle Park, N.C., have completed a preliminary evaluation of Spectra Science's LaserChip combinatorial chemistry technology. LaserChips are smart bead supports that speed the deconvolution and automated handling of synthesized compound libraries, enabling rapid screening of chemical libraries for drug discovery applications. Nabil M. Lawandy, president and CEO of Spectra Science, said the company is negotiating with a supplier of solid supports and automated chemistry systems to complete product development and market the LaserChips.
