A method for detecting a component of a biological system, which comprises contacting a biological component detecting device composed of a light reflecting substrate (I) substantially free from diffused reflection, a light interference layer (II) formed on the substrate (I), and a layer (III) of a substance for detecting said biological component provided at least in a region on the layer (II), with a solution presumed to contain the biological component to be detected, then forming a light-transmitting reflecting layer (IV) on its surface, and thereafter detecting the color of light interference or the brightness of the reflected light on the surface of the device.

A method for detecting a component of a biological system, which comprises providing a biological component detecting device composed of a light reflecting substrate (I), made of a metal or metal alloy itself or having a surface of a metal or metal alloy, and being substantially free from diffused reflection, a light interference layer (II) formed on the substrate (I), and a layer (III) of a substance for detecting said biological component provided at least in a region on the layer (II), wherein the light interference layer (a) does not have substantial reflecting characteristics to visible light, namely a wavelength of 300 to 800 nm, (b) has a thickness and refractive index controlled such that an increase in the thickness of the layer (III) appears as a change in interference color, and (c) has a surface with sufficient affinity for the layer (III); contacting said device with a solution containing the biological component to be detected; then forming a light-transmitting reflecting layer (IV) on its surface, wherein said layer (IV) is a layer of a metal; and thereafter detecting the color of light interference or the brightness of the reflected light on the surface of the device.
