From: Dual electrochemical sensing of spiked virus and SARS-CoV-2 using natural bed-receptor (MV-gal1)
The performance of the sensor for screening and specific detection of SARS-CoV-2 in vitro and clinical samples using DPV measured at a scan rate 50 mV s−1 in phosphate buffer (pH 7.4). (A) Screening of SARS-CoV-2 Antigen based on DPV images using the 1 µg/mL (e) to 500 fg/mL (a) on the MV-gal1/SCPE-GNP in vitro. (B) A calibration plot of the current density vs log concentration of SARS-CoV-2 Antigen. (C) Specific detection of SARS-CoV-2 Antigen based on DPV images using the 1 1 fg/mL (e) to 250 pg/mL. (D) A calibration plot of the current density vs log concentration of SARS-CoV-2 Antigen, in vitro. (E) SARS-CoV-2 Virus screening from clinical samples based on DPV. (F) A calibration plot of the current density vs log concentration of SARS-CoV-2 virus (copies/mL). (G) Detection of specific SARS-CoV-2 Virus from clinical samples based on DPV. (H) A calibration plot of the current density vs log concentration of SARS-CoV-2 virus (copies/mL).
