SiC-functionalized fluorescent aptasensor for determination of Proteus mirabilis

Aptamer-modified SiC quantum dots (DNA-SiC QDs) as fluorescent aptasensor are described for the determination of Proteus mirabilis. The SiC QDs were synthesized through one-pot hydrothermal method with particle sizes of about 14 nm. The amino-modified aptamers against P. mirabilis were conjugated to the surfaces of SiC QDs for bacteria recognition. The aptamer with an affinity for target protein can bound to P. mirabilis and this causes a...
