BIOCHIP SUBSTRATE

摘要

The object is to provide a biochip substrate which is suitable for high density and high precision immobilization of DNA probes by stamping and for fabrication of a biochip which secures a high S/N ratio and high spot homogeneity at each spot without blurring or other problems when used. A biochip substrate having a porous layer which contains inorganic particles such as silica particles or alumina particles and preferably has an average pore radius of from 1 to 100 nm and a pore volume of 0.1 to 5 cm 3 /g, on a base.
