African Swine Fever Virus (ASFV) is a DNA virus of the Asfivirus genus of the Asfarviridae family that is found in blood, body fluids, and internal organs. ASFV was described more than 40 years ago. This virus spreads pandemically and the mortality rate of the virus-related disease ranges from 90 to 100 %. The aim of this study was to propose the detection of specific nucleic acid of ASFV using electrochemical hybridization biosensor. Determination of DNA was conducted by AdTSV DPV a CV (potential 0 V, end potential -1.8 V, step potential 5 mV, modulation amplitude 25 mV, 0.2 M acetate buffer pH 5.0). The volume of analysed sample was 10 mu L. CV signals CA (log -0.0373x, r 0.99, Ep -1.30 V) and P peak (log -0.0801x, r 0.99, Ep -1.52 V) were observed. To increase the sensitivity, a modification of ODN with CdTe was proposed. The CdTe signal was observed around the potential of -0.56 V and for modified ODNs the signal was -0.58 V. SPION were prepared to capture DNA. The interaction of DNA (PCR fragment, 280 bp) with SPION was very fast within 30 s. The technique will be further used for a microfluidic system.
