Development of a low cost potentiostat using ATXMEGA32

Abstract

A primer on the use of commercial off-the-shelf software in the development of low cost launch control systems AIP Conf.Abstract. Potentiostat is principal devices in modern electrochemical research especially in the investigation of mechanism reaction which associated with the redox chemistry reaction and other chemical phenomena. Several applications measurement is developed based on this tool such as measurement of sample concentrations, quality test of food and medicine, environmental monitoring and biosensors or development of a protein sensor. We have developed a low cost, simple and portable potentiostat with a relatively small dimension. TLC2264 op-amp and ATMEGA32 microcontroller is used to build controller circuit system. Range potential measurement of this tool is between -1600mV and +1600mV within frequency range 1Hz -1 kHz. The developed instrument has been tested for measuring samples using different voltammetry techniques, like cyclic, square wave, and linear sweep with relative error under 2.5%.

Potentiostats for Protein Biosensing: Design Considerations and Analysis on Measurement Characteristics

“…Another similar example can be found in Muid et al [29]. Authors designed a low-cost potentiostat by focusing on its conditioning circuit.…”

“…3 Journal of Sensors system is similar to [28] but powered by RS-323. This study [29] did not investigate the detection of any particular protein; rather, it is focused on the designing of the potentiostat system ( Figure 6). Muid used the ATxmega32 microcontroller, which contains an internal DAC for the generation of waveforms with a sampling rate of 1 Ms/s and an internal ADC with a resolution of 12 bits and sample rate up to 2 MS/s.…”

“…Reprinted from [28]. Journal of Sensors overall design and performance of [29] made it eligible to be used for protein biosensing in an amperometric mode. Similar to [28], Kellner et al [30], and Kwakye and Baeumner [31], Molinari et al [32] also investigate the efficiency of a portable immunobiosensor designed for detection of β-casein (food allergen).…”

“…Considering the design, [33] used ADC with maximum resolution of 24 bits and DAC with a maximum resolution of 16 bits to reduce quantization error. Only [28][29][30][31][32][33][34] practically designed portable potentiostats that have the potential to be used for POC testing. The programmable, portable, and telemetric biosensor proposed by Jung et al [65] can be considered a great example of the POC biosensor, but it was designed for detection of a metabolite, ruthenium(III) chloride.…”
