Abstract

L'invention concerne un procédé de détection, un dispositif pour détecter la présence ou l'absence d'un ou plusieurs analytes cibles tels que des protéines, des acides nucléiques ou autres composés issus d'échantillons biologiques. Le procédé, le substrat et le coffret comprennent des sondes de capture et un oligonucléotide de capture co-immobilisé sur des points discrets sur le substrat pour obtenir un niveau ultrasensible de détection pour des analytes cibles tels que des protéines, de l'ADN, des peptides et des petites molécules.
