Patent ID: 7611888

Claim:
A solid substrate for a biochip comprising a compound represented by Formula 1 below: wherein R 1 , R 2 , and R 3 are each independently saturated or unsaturated linear C 2 -C 10 alkylene, ethyleneglycol oligomer, 1,4-substituted benzene, or 1,4-substituted pyridine; R 4 and R 5 are each independently hydrogen, an alkenyloxy group with an unsaturated bond end and a substituted or unsubstituted alkyl moiety of C 1 -C 20 , a carboxyalkylsulfinyloxy group with a substituted or unsubstituted alkyl moiety of C 1 -C 20 , a carboxyalkyloxy group with a substituted or unsubstituted alkyl moiety of C 2 -C 8 , an aminoalkyloxy group with a substituted or unsubstituted alkyl moiety of C 2 -C 8 , or a hydroxyalkyloxy group with a substituted or unsubstituted alkyl moiety of C 2 -C 8 ; X 1 and X 2 are each independently a positively charged functional group for ion-dipole interaction with an oxygen atom of cucurbituril or its derivative of represented by Formula 2; Y 1 is a functional group for a linkage with a biomaterial comprising a gene or a protein; and Y 2 is a functional group capable of binding to the solid substrate, wherein the compound of Formula 1 bonded to the solid substrate provides a linkage layer with a predetermined spacing in the biochip; and wherein a compound of Formula 3 Y 1 —R 1 —X 1 —R 2 —X 2 —R 3 —Y 2 (3) (wherein R 1 , R 2 , R 3 , X 1 , X 2 , Y 1 , and Y 2 are as defined in Formula 1 above) vertically passes through a cavity of cucurbituril or its derivative represented by Formula 2 (wherein n is an integer of 4 to 20; and R 4 and R 5 are as defined in Formula 1 above).
