  • Method for separating biological substances by using photoresist
    Patent number: 6194157
    Abstract: After a photoresist (2) is used to fix a biological sample, in order to obtain a particular biological substance, for example, a certain cell or biopolymer, from the biological sample embedded in the photoresist (2), properties of the photoresist are changed by exposing the portion of the photoresist (2) that covers the biological substance to light L which has an appropriate wavelength. The biological substance embedded in the changed photoresist is collected.
