Disposable multi-channel bio-analysis cartridge and capillary electrophoresis system for conducting bio-analysis using same
11531004 · 2022-12-20 · ·

A multi-channel bio-separation system configured to utilize a cartridge that has a individual, separate integrated reagent (i.e., a separation buffer) reservoir dedicated for each separation channel. The multiple channels may have different characteristics, such as different separation medium of different chemistries, different separation length, different channel sizes and internal coatings. In one embodiment, the cartridge does not include integrated detection optics. Not all channels need to be operative. One or more of the channels in the cartridge may be “dummy channels” that are not operative (e.g., not provided with a capillary tube). A capillary tube may be routed between the reservoir/electrode (anode) of one channel to an electrode (cathode) in another channel, thus allowing a longer length of capillary tube to be used to define a longer separation channel to improve resolution.

Systems, devices and methods for cell capture and methods of manufacture thereof

Embodiments of the current disclosure are directed to systems, methods and apparatus for evaluating single cell secretion profiles. In some embodiments, the apparatus may be configured to analyze substances expressed by a biological cell and may include a first compressible substrate, and a second substrate configured for removable sealing attachment with the first substrate. In some embodiments, upon attachment of the second substrate with the first substrate, an assembly is formed such that the open side of the plurality of chambers are covered by the second substrate, and a portion of each of the plurality of capture areas are exposed in each of the chambers.

Method to monitor and control the temperature of a sample holder of a laboratory instrument

A method to monitor and control the temperature of a sample holder of a laboratory instrument during execution of a temperature profile on the sample holder is presented. The laboratory instrument comprises a sample holder with high temperature uniformity and at least three identical temperature sensors. The measured actual temperatures of the sample holder are processed in order to determine if the execution of the temperature profile should be continued or aborted. Furthermore, temperature sensors which measure actual temperatures that do not fulfil certain requirements are excluded from further monitoring and controlling the temperature of a sample holder.

Safety light curtain to disable carousel rotation
11519925 · 2022-12-06 · ·

A digital slide scanning apparatus includes a safety light curtain that operates to disable the motor that rotates the carousel when the presence of an object (e.g., the fingers of an operator) is detected within a predetermined area of the carousel. The light curtain also operates to disable the motor that rotates the carousel when an improperly positioned glass slide or slide rack is detected. The digital slide scanning apparatus also includes a multi-color status indicator for each rack slot that indicates the rack slot location of an improperly positioned glass slide or slide rack.

Structure and method to use active surface of a sensor
11519846 · 2022-12-06 · ·

Disclosed is an apparatus and method of forming, including a supporting structure, a sensor on the supporting structure, a pair of columns on the supporting structure at opposite sides of the sensor, the pair of columns having a column height relative to a top surface of the supporting structure, the column height being higher than a height of the active surface of the sensor relative to the top surface of the supporting structure, and a lidding layer on the pair of columns and over the active surface, the lidding layer being supported at opposite ends by the pair of columns. The active surface of the sensor, the lidding layer and the pair of columns form an opening above at least more than about half of the active surface of the sensor, and the supporting structure, the sensor, the lidding layer and the pair of columns together form a flow cell.

Microfluidic chip

A microfluidic chip orients and isolates components in a sample fluid mixture by two step focusing, where sheath fluids compress the sample fluid mixture in a sample input channel in one direction, such that the sample fluid mixture becomes a narrower stream bounded by the sheath fluids, and by having the sheath fluids compress the sample fluid mixture in a second direction further downstream, such that the components are compressed and oriented in a selected direction to pass through an interrogation chamber in single file formation for identification and separation by various methods. The isolation mechanism utilizes external, stacked piezoelectric actuator assemblies disposed on a microfluidic chip holder, or piezoelectric actuator assemblies on-chip, so that the actuator assemblies are triggered by an electronic signal to actuate jet chambers on either side of the sample input channel, to jet selected components in the sample input channel into one of the output channels.

Flow control in microfluidic router
11511275 · 2022-11-29 · ·

A method for detecting, sorting, purifying and characterizing objects of interest in a liquid sample. The method comprises preparing, in a preparation module ON) of a microfluidic router system, the liquid sample for processing. Preparing comprises transporting the sample through a microfluidic channel, and forwarding the prepared sample from an outlet of the preparation module into an inlet of a routing module. Forwarding comprises coupling a microfluidic flow between the outlet and the inlet to passively buffer against or actively compensate for variations in a flow rate of the prepared sample at the outlet, and diverting the objects of interest from the microfluidic flow. Forwarding the sample comprises sensing a flow characteristic of the sample in preparation, routing module, or in flow connection, and controlling a flow control element taking the sensed characteristic into account to compensate for a variation in the flow rate by a closed-loop flow control.
