Abstract: A biosensor, a method of making the same, and a molecule detection method for detecting target molecules comprises a heat-shrinkable film. The heat-shrinkable film is made of a thermoplastic material shrinkable when heated and a plurality of antigen molecules are adsorbed to the heat-shrinkable film. The method of making a biosensor involves the steps of: (a) providing a heat-shrinkable film made of a thermoplastic material shrinkable when heated; (b) providing an antigen solution, the antigen solution having a plurality of antigen molecules; and (c) soaking the heat-shrinkable film in the antigen solution for at least 10 minutes. The molecule detection method involves the steps of: (a) providing the biosensor; (b) providing a substance under detection and allowing the substance under detection to come into contact with the biosensor; and (c) detecting a signal outputted by the biosensor upon contact with the substance under detection.

Abstract: A method for preparing an elastic conductive fiber includes: immersing an elastic fiber in a first treating composition containing a metal trifluoroacetate and an alcohol solvent, so as to obtain a processed elastic fiber containing the metal trifluoroacetate; and immersing the processed elastic fiber in a second treating composition containing water, a reducing agent and a nano conductive material, so that a metal particle is formed on a surface of the processed elastic fiber by reducing metallic ions in the metal trifluoroacetate, and the nano conductive material is deposited on a surface of the processed elastic fiber and a surface of the metal particle. An elastic conductive fiber is also disclosed.
