Solid-state colorimetric biosensors having sensory groups and interdendritic cross-linking segments of alternating conjugated double and triple bonds are prepared by intermolecular polymerization of diacetylene-functionalized dendritic polymer precursors. The polymerization process may be used to form solid films that are capable of indicating the presence of an analyte by a detectable change in color. The disclosed solid-state calorimetric biosensors may exhibit excellent stability at elevated temperatures and in the presence of organic solvents, and due to the dendritic architecture and high density of sensing functionality achieve high sensitivity to analytes.
通过二乙炔官能化树枝状聚合物前体的分子间聚合,制备出具有感官基团和交替共轭双键和三键树枝状交联段的固态比色生物传感器。聚合过程可用于形成固体薄膜,这种薄膜能够通过可检测到的颜色变化来指示分析物的存在。所公开的固态热量测定生物传感器可在高温和有机溶剂存在下表现出优异的稳定性,并且由于树枝状结构和高密度传感功能,可实现对分析物的高灵敏度。
