Abstract: The present subject matter provides a High Mobility Electron Transistor (HEMT) comprising: a substrate, a nucleation layer provided on the substrate, a channel layer, and a buffer layer formed between the nucleation layer and the channel layer. The buffer layer comprises a vertical stack of p-n junctions. Each p-n junction of the vertical stack of p-n junctions comprises an n-type layer provided on a p-type layer. The n-type layer and the p-type layer are parallel to the substrate.

Abstract: An electrochemically active, creatinine-binding device is provided to detect and measure quantitatively, creatinine in biological samples. The device of the present invention is also provided with a device to detect and measure quantitatively creatinine and albumin bioanalytes, simultaneously and to determine albumin to creatinine ratio (ACR). The present invention also provides an electrochemically active, creatinine-binding and albumin-binding device, for collection and retention of biological samples, having creatinine and albumin bioanalytes. In the present invention, a device holder is provided to receive the electrochemically active, creatinine-binding and albumin-binding device. The device, point-of-care biosensor and the method of the present invention, facilitate quantitative measurement of creatinine and albumin bioanalytes in urine and blood samples, and albumin to creatinine ratio (ACR), in urine samples, electrochemically, by determining redox current values.
