Devices and methods for the detection of nucleic acids (e.g., RNA, DNA) are described. The nucleic acid can be obtained or derived from a pathogen, such as a virus. In one embodiment, the virus is a coronavirus (e.g., SARS-CoV-2) related to the disease COVID-19. Accordingly, devices and methods may be used in the field as point-of-care devices to test a subject (e.g., a patient) for the presence of the SARS-CoV-2 virus or another nucleic acid.

The present invention provides a system and method for building and optimizing biosensors to create a multi-layered bio-sensing system by incorporating two different formats comprised of i) a single wall carbon tubular sensing element and ii) a non-tubular graphene sensing element. This multi-layered system allows for assaying molecules across a large range of molecular weights by sensing molecules in both gas and liquid from a common sample simultaneously. By collecting and analyzing both larger, heavier molecules, including, but not limited to: proteins hormones, nucleic acids, lipids, lipoproteins, etc., with non-tubular graphene sensors and smaller, lighter volatile organic compounds (VOCs) as emitted in gas form from the same sample are assayed with single walled-carbon nanotubules (SWNTs), this invention provides a more complete, holistic understanding of the organism's current state of health.

A method for providing quantitative information for targets and a device using the same according to an exemplary embodiment of the present disclosure are provided. A quantitative information providing method for targets according to the exemplary embodiment of the present disclosure includes flowing a plurality of microdroplets into a chamber or a channel including a detection region acquiring a single layer of microdroplets in which the plurality of microdroplets is present as a single layer, and providing quantitative data of targets based on the single layer image of the microdroplets, and the detection region has a height which is one time to about two times of a diameter of the plurality of microdroplets and is defined as a region in which the plurality of microdroplets is dispersed in a plurality of columns to fill the detection region.
