Point of care sensor systems
First Claim
1. A cartridge comprising:
- a sample inlet chamber for receiving a sample;
a detection channel providing a flow path over a first sensor surface coated with an enzyme and a second sensor surface having a capture species attached thereto, wherein the cartridge is configured for non-capture enzymatic sensing and enzyme-linked immunosorbent assay (ELISA) sensing on the sample in the detection channel.

Abstract
Provided are point of care sensor systems that include portable readers and disposable cartridges for receiving and analyzing samples. A cartridge may be equipped with one or more sensor channels, each containing one or more sensors. After providing a sample to a cartridge, the cartridge can be inserted into a reader, which can interact with the cartridge to perform on-cartridge sensing and receive signals indicating the presence and/or quantity of one or more targets in the sample. Examples of cartridges can include cardiac panels, sepsis panels and the like. In some embodiments, the same sensor hardware may be configured for multiple measurements of different targets conducted at different time frames. Also provided herein are novel on-cartridge solid and liquid reagent storage and delivery mechanisms.
