Patent number: 11406957Abstract: The present disclosure relates to processes for suspending stretched nucleic acids over surface features. These processes can be used to prepare stretched nucleic acids that are more active in enzymatic reactions and other reactions than those laid down on a flat surface. These processes can be achieved by using a photoresist layer on top of a substrate, stretch a nucleic acid on top of the surface, and then remove part of the photoresist to form surface features that suspend the stretched nucleic acid. Furthermore, the formation of a hydrogel layer over the stretched nucleic acid and the surface features can transfer the stretched nucleic acid to the hydrogel for further reactions, including enzymatic reactions.Type: GrantFiled: April 12, 2019Date of Patent: August 9, 2022Assignee: CENTRILLION TECHNOLOGY HOLDINGS CORPORATIONInventors: Maurizio Righini, Wei Zhou

Patent number: 10376888Abstract: A reagent storage and dispensing apparatus comprises a housing, storage wells disposed within an internal volume of the housing, and a valve. The housing comprises a shared outlet chamber. The wells can be selected to be in fluid communication with the shared outlet channel through individual outlet channels. The valve is coupled to the housing and is rotated to select a well to be in fluid communication with the shared outlet channel while preventing the remaining wells from being in fluid communication. As the valve is rotated, the wells and their individual outlet channels remain stationary. To dispense fluid from or draw fluid into the selected well, positive or negative pressure, respectively, is introduced into the internal volume. Pressurization of the internal volume also pressurizes the plurality of wells, though the valve allows only fluid flow for the selected well.Type: GrantFiled: July 1, 2015Date of Patent: August 13, 2019Assignee: CENTRILLION TECHNOLOGY HOLDINGS CORPORATIONInventors: Jeremy Cheng, Wei Zhou
