Highly sensitive and decomposable quantum dot nanosphere probe and preparation method thereof
ActiveCN107462705AEnhanced detection signalGood dispersionBiological testingBiotin-streptavidin complexFluorescence
The invention discloses a highly sensitive and decomposable quantum dot nanosphere probe and a preparation method thereof. Through a fulcrum-mediated strand displacement reaction, a DNA hairpin probe modified by three desulfated biotins is self-assembled into a Y-type DNA nanostructure; and the Y-type DNA structure and quantum dots coupled to streptavidin are self-assembled to form the quantum dot nanosphere probe. The prepared quantum dot nanosphere probe and an immunomagnetic separation technology are combined to be applied to quick detection of a target analyte. Because of a binding force between biotin and streptavidin stronger thana binding force of desulfurized biotin, the quantum dot nanosphere probe is decomposed, and thus quantum dots are released; the target analyte concentration is determined by detecting the fluorescence value of a quantum dot solution, and a shielding effect of immunomagnetic beads on the quantum dots is overcome. The method has high sensitivity and the detection limit of microorganisms is 1.37 cfu / mL. This method is good in specificity, and common other microorganisms do not affect the detection.
