Polydiacetylene-coated polyvinylidene fluoride strip aptasensor for colorimetric detection of zinc(II)
We report a new polydiacetylene (PDA) sensor strip for simple visual detection of zinc ions in aqueous solution. The specificity of this sensor comes from Zn2+ DNA aptamer probes conjugated onto PDA. Effects of aptamer length and structure on the sensitivity of PDA’s color transition were first inve...
