A Pencil-Lead Immunosensor for the Rapid Electrochemical Measurement of Anti-Diphtheria Toxin Antibodies
Autor: Wilson A. Ameku, Vanessa N. Ataide, Eric T. Costa, Larissa R. Gomes, Paloma Napoleão-Pêgo, David William Provance, Thiago R. L. C. Paixão, Maiara O. Salles, Salvatore Giovanni De-Simone
Publikováno v: Biosensors, Vol 11, Iss 12, p 489 (2021)
Diphtheria is a vaccine-preventable disease, yet immunization can wane over time to non-protective levels. We have developed a low-cost, miniaturized electroanalytical biosensor to quantify anti-diphtheria toxin (DTx) immunoglobulin G (anti-DTx IgG)
