ABSTRACT
This technical note presents a simple and disposable lab-on-a-tube (LOT) for point-of-care measurements of multiple analytes. LOT is a one-step device that can perform both sample collection and multi-sensing on-site. Sample collection is conducted by taking advantage of its inherent micro/macro channel structure while multi-sensing is conducted by integrated microsensors. This approach ensures reliable transportation of various samples into the testing area by either passive capillary force or active suction force, thus avoiding the need for a pump or injection components as used in lab-on-a-chip systems. The developed LOT (Diameter = 1 mm, Sensing length = 4.5 mm, Required sample volume = 3.5 microl) is capable of simultaneously quantifying the concentrations of glucose, lactate and oxygen in human serum samples. The result suggests the LOT hold great potential for many point-of-care applications.
