Development of electronic modules for their integration with impedimetric transducers applied to sarcosine detection
Abstract The development of fast, simple, sensitive, and minimally invasive biosensors for detecting diseases, conventionally need specialized, expensive, and highly invasive instrumentation. Furthermore, such biosensors pertinently also, need the development of optoelectronic modules that are capable of implementing specific detection techniques while interacting with the user through a friendly interface. This work highlights the development of a system whose hardware and software contributes to the detection of analytes by impedimetric sensors, especially emphasizing on the detection of sarcosine, a natural amino acid associated with prostate cancer (PCa). Dummy circuits coupled with impedimetric transducers were used to perform precise measurements using a sinusoidal signal of 20 mV in the range from 0.1 Hz to 1 MHz.
