Methods for optically immobilizing very small objects and their use

摘要

A method for optically immobilizing very small objects, where a material with the capability of photoinduced deformation to possibly immobilize very small objects is used at least as a surface layer of a carrier and where the very small objects are immobilized via irradiation light while they are arranged on the surface of the carrier. Very small objects particularly preferably include proteins, nucleic acids and the like. A very small object-immobilized carrier having immobilized very small objects in such manner, particularly a biosensor. A method for observing a very small object immobilized on the surface of a carrier by an appropriate approach giving displacement force to the very small object. The present invention provides a method for strongly immobilizing very small objects on the surface of a carrier with a simple tool.
