BIOCHIP SUBSTRATE AND BIOCHIP

摘要

A substrate for biochips with which spots are not diffused and cross-contamination due to contacts between adjacent spots does not occur, as well as a biochip using the substrate, is disclosed. A substrate for biochips with which spots are not diffused and cross-contamination due to contacts between adjacent spots does not occur, by forming a plurality of recesses for immobilizing biologically relevant substances, as well as a biochip using the substrate, was provided. It was discovered also that the desired binding of target molecules in a test sample occurs at a detectable level in solution systems even if the volume of each recess is extremely small as small as 1 nL to 10 nL.
