摘要:
The present invention provides a method of manufacturing a structured substrate, the method comprising: providing a working substrate (522) having a side surface (524) and an array of reaction cavities (526), each of the reaction cavities (526) having an opening along the side surface (524) and extending a depth from the corresponding opening into the working substrate (522), the reaction cavities (526) coinciding with an array plane (525); and directing a deposition stream (536) onto the working substrate (522) at a non-orthogonal angle (544) with respect to the array plane (525), the deposition stream (536) including a plasmon resonant material, wherein the working substrate (522) forms a shadow area (558) and an incident area (560) in each reaction cavity (526) relative to a path of the deposition stream (536) such that the plasmon resonant material of the deposition stream (536) is blocked by the side surface (524) from being deposited onto the shadow area (558) and is permitted to pass through the opening and form along the incident area (560).

Systems and methods for conducting designated reactions utilizing a base instrument and a removable cartridge. The removable cartridge includes a fluidic network that receives and fluidically directs a biological sample to conduct the designated reactions. The removable cartridge also includes a flow-control valve that is operably coupled to the fluidic network and is movable relative to the fluidic network to control flow of the biological sample therethrough. The removable cartridge is configured to separably engage a base instrument. The base instrument includes a valve actuator that engages the flow-control valve of the removable cartridge. A detection assembly held by at least one of the removable cartridge or the base instrument may be used to detect the designated reactions.

Provided herein is a droplet actuator including (a) first and second substrates separated by a droplet-operations gap, the first and second substrates including respective hydrophobic surfaces that face the droplet-operations gap; (b) a plurality of electrodes coupled to at least one of the first substrate and the second substrate, the electrodes arranged along the droplet-operations gap to control movement of a droplet along the hydrophobic surfaces within the droplet-operations gap; and (c) a hydrophilic or variegated-hydrophilic surface exposed to the droplet-operations gap, the hydrophilic or variegated-hydrophilic surface being positioned to contact the droplet when the droplet is at a select position within the droplet-operations gap.
