Ultrasensitive Detection of Lysozyme upon Conformational Change of DNA Duplex

Figure 6

Nonspecific binding of different interfering proteins with concentration of 10 nM on the nanoaptasensor’s surface compared to the specific binding of lysozyme with concentration of 500 pM. (a) The UV/Vis spectra and color response of designed assay to lysozyme in comparison with other proteins; (b) specificity of designed assay in the presence of different proteins.
