摘要：
Triangular silver nanoprisms were prepared and applied to make colorimetric detection of cysteine based on our findings that cysteine could lead to the blue shift of the dipole plasmon resonance absorption,but other 19 kinds of natural amino acids could not. Cysteine with a concentration 160nmol/L can result in a color change that can be discerned with naked eyes.
