  • Biochemical carriers capable of storage, preservation and indexing and method for fabricating the same
    Patent number: 11987693
    Abstract: Biochemical carriers are provided. Each of the biochemical carriers includes: biochemical molecules having a sequence into which digital data information is encoded; a carrier particle composed of a polymer matrix and in which the biochemical molecules are connected to the surface or inside of the polymer matrix; and an index code introduced into the carrier particle. Also provided is a method for fabricating biochemical carriers. The fabrication method includes: encoding digital data into a sequence of biochemical molecules; synthesizing the biochemical molecules based on the encoded sequence; mixing the biochemical molecules with a photocurable material; curing the mixture to obtain carrier particles including a polymer matrix; and introducing an index code into the carrier particles simultaneously with or separately from the curing. Also provided is a method for restoring digital data from the biochemical carrier.
