Description
あるいは、先端部が覆われるほど厚く薄膜を形成した後、エッチングにより、先端部を露出することもできる。露出部にプローブDNA分子を固定するには、金属構造体表面と薄膜表面との化学的性質の差を利用するのが良い。たとえば、金属が金で金属を覆う膜がSiO2の場合には、プローブDNAの末端に予めチオール基を修飾して置くことで、プローブDNA水溶液をSiO2被覆膜形成後にアプライすると、金露出部のみにプローブDNAが固定される。金属構造体の適切な大きさは、照射する光の波長によって異なる。すなわち、表面プラズモンの発生に適する共鳴周波数は、金属構造体表面の自由電子群と光との相互作用によるものである。励起光を可視光とすると、金属構造体の大きさは、幅・高さともに、30から1000nm程度が適しているが、この条件に縛られるものではない。また、上記方法により、先端部にDNAプローブを固定した後、金属構造体を覆う薄膜を除去しても、表面プラズモンによる効果は同等である。金属構造体を覆う薄膜が、核酸分析デバイスとしての特性に悪影響を与える場合には、除去することが好ましい。
