Disclosed are methods, systems, and articles of manufacture for performing a process on biological samples. An analysis of biological samples in multiple regions of interest in a microfluidic device and a timeline correlated with the analysis may be identified. One or more region-of-interest types for the multiple regions of interest may be determined; and multiple characteristics may be determined for the biological samples based at least in part upon the one or more region-of-interest types. Associated data that respectively correspond to the multiple regions of interest in a user interface for at least a portion of the biological samples in the user interface based at least in part upon the multiple identifiers and the timeline. A count of the biological samples in a region of interest may be determined based at least in part upon a class or type of data using a convolutional neural network (CNN).
ELECTRONICALLY-CONTROLLED DIGITAL FERROFLUIDIC DEVICE AND METHOD FOR SCALABLE AND ADDRESSABLE BIOANALYTICAL OPERATIONS
An electronically-controlled digital ferrofluidic device is disclosed which employs a network of individually addressable coils in conjunction with one or more movable permanent magnets, where each moveable permanent magnet delivers the designated fluid manipulation-based tasks. The underlying mechanism facilitating fluidic operations is realized by addressable electromagnetic actuation of miniaturized mobile magnets that exert localized magnetic body forces on droplets filled with magnetic nanoparticles. The reconfigurable, contactless, and non-interfering magnetic-field operation properties of the underlying actuation mechanism allow for the integration of passive and active components to implement advanced and diverse operations with high efficiency (e.g., droplet sorting, dispensing, generation, merging, mixing, filtering, and analysis).

SYSTEM AND METHODS FOR ANALYZING BIOSENSOR TEST RESULTS
A system for analyzing biological specimens by spectral imaging includes a biosensor comprising at least one graphene layer on a substrate and a memory in communication with a processor. The biosensor is configured to acquire a biological specimen sample. The memory and the processor are configured to conduct Raman spectroscopy to obtain spectral data for the sample, transmit the spectral data to a hub for direct or indirect transmission to one or more servers, perform multivariate analysis on the spectral data, and deliver a report based on the multivariate analysis of the spectral data.
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.

The present application pertains inter alia to an isolated vertebrate cell suitable for recombinant expression of a polypeptide of interest, wherein the vertebrate cell is altered to impair the function of the endogenous protease matriptase and wherein the cell comprises at least one heterologous polynucleotide encoding a polypeptide of interest and wherein the polypeptide of interest is secreted by the cell. It was found that using respective vertebrate cells for producing a recombinant polypeptide of interest significantly reduces clipping of the polypeptide of interest that is secreted into the cell culture medium. Also provided are improved production and screening methods.
