1. A method for the preparation of metal colloid monolayers or submonolayers comprising the steps of:

  • a.) selecting a substrateb.) coating the substrate with a bifunctional organic film to impart to said substrate a functionality that allows for bonding of metal colloid particles; and

    c.) contacting the organic film coated substrate with a solution of colloid metal particles to bind said particles to the functional groups on said organic film thereby forming said monolayer or submonolayer,said method resulting in an organic film coated substrate containing a surface layer of colloidal metal particles that are closely spaced, predominately unaggregated and confined to nearly a single plane.
