Abstract:
1. A method of forming a fine particle array on a substrate which comprises: a step A of fixing metal oxide fine particles and protein complexes comprising a hollow protein, which includes said metal oxide fine particle therein, on said substrate, a step B of removing said hollow protein while leaving said metal oxide fine particles on said substrate after said step A, a step C of covering said metal oxide fine particles by depositing an insulating layer having a film thickness of 3 nm or greater and 100 nm or less, which is hardly reduced compared to said metal oxide fine particles, on said substrate on which said metal oxide fine particles were disposed, and a step D of reducing said metal oxide fine particles covered by said insulating layer by subjecting the substrate, on which the insulating layer was deposited in said step C, to a heat treatment in a reducing atmosphere.
