    摘要: Chemically-modified surfaces on unoxidized carbon, silicon, and germanium substrates are disclosed. Ultraviolet radiation mediates the reaction of protected &ohgr;-modified, &agr;-unsaturated aminoalkenes (preferred) with hydrogen-terminated carbon, silicon, or germanium surfaces. Removal of the protecting group yields an aminoalkane-modified silicon surface. These amino groups can be coupled to terminal-modified oligonucleotides using a bifunctional crosslinker, thereby permitting the preparation of modified surfaces and arrays. Methods for controlling the surface density of molecules attached to the substrate are also disclosed.

    摘要: Chemically-modified surfaces on unoxidized, bromine- or iodine-terminated carbon, silicon, and germanium substrates are disclosed. Visible light mediates the reaction of protected &ohgr;-modified, &agr;-unsaturated aminoalkenes (preferred) with bromine- or iodine-terminated carbon, silicon, or germanium surfaces. Removal of the protecting group yields an aminoalkane-modified silicon surface. These amino groups can be coupled to terminal-modified oligonucleotides using a bifunctional crosslinker, thereby permitting the preparation of modified surfaces and arrays. Methods for controlling the surface density of molecules attached to the substrate are also disclosed.

    摘要: The present invention is thus directed to an automated system and method of varying the optical path length in a sample that a light from a spectrophotometer must travel through. Such arrangements allow a user to easily vary the optical path length while also providing the user with an easy way to clean and prepare a transmission cell for optical interrogation. Such path length control can be automatically controlled by a programmable control system to quickly collect and stores data from different path lengths as needed for different spectrographic analysis. Such a methodology and system, as presented herein, is able to return best-match spectra with far fewer computational steps and greater speed than if all possible combinations of reference spectra are considered.
