Systems, devices and methods for cell analysis provide an end user with real-time cell analysis and imaging of single cells in a population. Various cell analysis systems can provide both optical imaging, as well as electroscopic imaging, which is an image of cellular response as detected by sensors covering a cell footprint or cellular efflux. An automated fluidic system can provide an end-user selected sequence of reagents to cells, while precision controlled sensor array device thermostatting, and analysis compartment environmental control provide consistency in the cell analysis system environment.

Described herein is novel, economical device for photodetection of presence of a target nucleic acid in a sample. Accordingly, the detection takes place based on difference in light intensities. The invention further describes the method and apparatus for detection of target nucleic acid using said device.

An ribonucleic acid (RNA) detection device is disclosed, comprising a case, a substrate, at least one display component, and a processing circuit board, wherein one plane on the substrate includes an RNA detection panel and a metal mask cover covering the RNA detection panel, and, when a specimen liquid is dropped onto the RNA detection panel through the detection hole of the case and the concave opening of the metal mask cover, the signal generated by the contact of the specimen liquid with the RNA detection panel is received via the sensor circuit board thus generating the specimen signal determination value which then transferred to the processing circuit board so that the processing circuit board determines whether the specimen liquid includes the virus based on the specimen signal determination value.

This disclosure relates to portable devices for SARS-COV-2 Antigen (SC2A), a biomarker for the detection of Coronavirus disease 2019 (COVID19). Diagnosis of viral infections such as SARS-COV-2 can be obtained in the early stages of a disease by detection of viral antigens (e.g., SC2A) directly in the clinical specimen.

Techniques for antenna positioning system having a drive element shared by multiple antennas for positioning about a positioning degree of freedom are described. In some examples, each antenna can be coupled with a rotating spindle, with each antenna spindle being coupled with the shared drive element. By driving a shared drive element, each of the antenna spindles in the system can be rotated via the associated coupling. In some examples, such a coupling may include link arms with an adjustable length to reduce backlash or to apply a preload to the system. In some examples, such a coupling may be configured to position multiple antennas over different orientation ranges in response to the drive element driving over an actuation range, which may include one antenna being idled or otherwise maintained at an orientation while another antenna is driven, or may include different antennas being driven according to different actuation ratios.

A biosensor cartridge can include a circuit board including a connection terminal electrically connectable to an external diagnostic device; a sensor chip detecting a target material from an applied analysis specimen, having a reactant reacting specifically with the target material, and transmitting an electrical signal generated by reacting with the detected target material to the connection terminal of the circuit board; and a housing accommodating the circuit board and the sensor chip and surround the circuit board and the sensor chip so that the connection terminal is exposed. The housing has an inclined surface dent from an upper surface and forms an accommodating portion that exposes the sensor area of the sensor chip and accommodates the test specimen. Further, the accommodating portion includes a pattern structure for lowering surface energy.
