| titleOfInvention | Exosome enrichment chip based on chitosan positive and negative charge adsorption principle and preparation method thereof |
| abstract | An exosome enrichment chip based on a chitosan positive and negative charge adsorption principle and a preparation method thereof are disclosed, which comprises the following components: the upper layer is a straight channel liquid path layer, and the lower layer is a triangular column mixed flow liquid path layer; the device is specifically provided with the following structures: sample introduction port, sample separation zone and sample outlet. The preparation method of the exosome-enriched chip based on the chitosan positive and negative charge adsorption principle comprises the following steps: preparing a photoresist template with a raised channel part; developing and hardening; treating the template with a silylating agent; obtaining a polydimethylsiloxane chip with a structure; and (4) irreversible sealing. The invention has the advantages of simple structure, convenient preparation and operation, high speed, high efficiency and wide application range. |
