Here, dual epitope imprinted polymer electrode (DEIP) matrix was fabricated on gold surface of electrochemical quartz crystal microbalance (EQCM) for recognition of target epitope sequence in blood samples of patients suffering from brain fever. Epitope sequences from outer membrane protein Por B of <jats:italic>Neisseria meningitidis<\/jats:italic> (MC58) bacteria predicted through immunoinformatic tools were chosen for imprinting. Self\u2010assembled monolayers (SAM) of cysteine appended epitope sequences on gold nanoparticles were subjected to polymerization prior to electrodeposition on gold coated EQCM electrode. The polymeric matrix was woven around the cysteine appended epitope SAMs through multiple monomers (3\u2010sulfo propyl methacrylate potassium salt (3\u2010SPMAP), benzyl methacrylate (BMA)) and crosslinker (N, N\u2032\u2010methylene\u2010<jats:italic>bis<\/jats:italic>\u2010acrylamide). On extraction of the peptide sequences, imprinted cavities were able to selectively and specifically bind targeted epitope sequences in laboratory samples as well as \u2018real\u2019 samples of patients. Selectivity of sensor was examined through mismatched peptide sequences and certain plasma proteins also. The sensor was able to show specific binding towards the blood samples of infected patients, even in the presence of \u2018matrix\u2019 and other plasma proteins such as albumin and globulin. Even other peptide sequences, similar to epitope sequences only with one or two amino acid mismatches were also unable to show any binding. The analytical performance of DEIP\u2010EQCM sensor was tested through selectivity, specificity, matrix effect, detection limit (0.68\u20131.01\u2009nM), quantification limit (2.05\u20133.05\u2009nM) and reproducibility (RSD\u2009~\u20095%). Hence, a diagnostic tool for bacterium causing meningitis is successfully fabricated in a facile manner which will broaden the clinical access and make efficient population screening feasible.<\/jats:p>","DOI":"10.1002\/jmr.3087","type":"journal-article","created":{"date-parts":[[2024,4,30]],"date-time":"2024-04-30T10:24:57Z","timestamp":1714472697000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Dual
