The present disclosure provides an achromatic colorimetric nanosensor, by using a mixture of nanoparticles with complementary colors. The color changes from an achromatic color to a chromatic color enables more clear color-transition and, thus, allows immediate analysis of the presence of a target analyte. Further, the present disclosure provides achromatic colorimetric nanosensor for detection of multiple analytes using plural nanoparticles via color changes from an achromatic to multiple chromatic colors.
