Device for Detection of Organic Compounds, Ions, and Other Molecular Species by Optical Interference in a Porous Silicon Layer

技术优势

This invention has excellent applications to homogeneous assay systems because organic compounds can be detected in solutions without separating them, removing the burdensome step of washing out the compounds. This method may be performed using nanoliters of reactants.

详细技术说明

This chemistry provides a means to sensitively measure the quantity of a chemical compound or element of interest (analyte) by measuring the effect it has on the optical interference spectrum from a layer of porous silicon that may or may not have been modified to enhance the binding of the analyte.

*Abstract

Combinatorial chemistry is arguably the most important development in the drug discovery process in over a decade. However, the detection of significant biological events in high throughput screening involves many burdensome tasks, and often includes the separation of the products of reaction before detection can take place.

Title: Porous semiconductor-based optical interferometric sensor
Usefulness: Porous semiconductor-based optical interferometric sensor
Summary: USE The methods can be used for the highly sensitive detection, identification and quantification of small molecules and particularly small organic molecules (e.g. carbon-containing molecules, e.g. biotin, and the steroid digoxigenin), short DNA oligonucleotides (e.g. 16-mers), and proteins (e.g. streptavidin and antibodies), or inorganic species such as metal ions.
Novelty: New assays for the detection of analytes using a porous semiconductor substrate having a binder compound associated with it and using Fabry-Perot fringe wavelength measurement
