A multipedal DNA walker for amplified detection of tumor exosomes.
Chemical communications (Cambridge, England) 2020 May 07Sizes of these terms reflect their relevance to your search.
We have fabricated an ultrasensitive exosome biosensor based on a multipedal DNA walker with a core of target exosomes. Specific recognition is achieved by introducing a CD63 aptamer and facile separation is obtained with magnetic Fe3O4@Au nanoparticles. A limit of detection down to 6/μL is obtained with excellent selectivity.
