A substrate for the immobilization of proteins is made by treating a carrier with an amino group-containing silicon compound represented by the following general formula: (RO)3Si—(CH2)k—(C6H4)1—(CH2)m—(NHCH2CH2)n—NH2 (wherein R is an alkyl group, and k is 1, 2, 3 . . . , l is 0, 1, 2, 3 . . . , m is 0, 1, 2, 3 . . . , and n is 1, 2, 3 . . . ).
摘要:
A masking pattern is performed on a substrate by using materials that are weakly adhered to the substrate, and then the masked substrate is etched. Since the mask is weakly adhered to the substrate, the mask is peeled off from the surface of the substrate, so that a gap is generated between the mask and the substrate, and then anisotropic etching is performed. According to this method, it is possible to easily manufacture an optical measurement substrate having recesses whose sectional shape can be approximated to a curve having inflection points. Therefore, optical characteristics of a minute amount of substances can be evaluated efficiently without the loss of incident and reflected light even when measuring light is incident at an angle of less than 45 degrees.

Concave parts arranged with a predetermined pattern on the surface of a plate substrate is formed. Wettability of the concave part surface is made to differ from that of the surface of a flat part between the concave parts. Particularly, in the case of an aqueous liquid, by forming water repellency film on the flat part, liquid can be stably retained on the concave part and prevented from spilling over to the adjacent concave part.
