Abstract:
1. A method of analyzing a target in a sample comprising: contacting the sample with a capturing probe DNA conjugated to both a magnetic bead (MB) and a first quantum dot (QD) and further contacting the sample with a signaling probe DNA covalently labeled with a second QD; hybridizing a target with the capturing probe and the signaling probe DNA to a target to form a hybridized target, wherein the target is selected from the group consisting of: a single wall carbon nanotube (CNT), a multi-wall CNT, a genomic substance, a single strand DNA, a double strand DNA, and a combinations thereof; separating the hybridized target using a magnetic field; and quantifying the target by measuring the ratio of light emission from the second QD to the light emission from the first QD, wherein the method is resistant to an inhibitory substance and/or an interference substance present in the sample or introduced during performance of the method.
