A new type of pH-responsive indole-based (4-HINF) hydrogel, fabricated by a sol-gel method, was utilized as a platform for colorimetric detection of urea in aqueous solution. The colorimetric sensor was established by virtue of the synergistic effect of cation-π interaction and hydrogen bonding with good regenerative ability. The results exhibited linear response in the range of 0-10 mM with a limit of detection of 10 μM. The prepared 4-HINF hydrogel possessed high selectivity to pH change under complicated environments ensuring further applications in environmental and bio-systems.
一种通过溶胶-凝胶法制备的新型pH响应性吲哚基（4-HINF）水凝胶被用作水溶液中尿素比色检测的平台。该比色传感器是通过阳离子-π相互作用和氢键的协同效应建立的，具有良好的再生能力。结果表明在0-10 mM范围内呈线性响应，检测限为10 μM。所制备的4-HINF水凝胶在复杂环境下对pH变化具有高选择性，确保了在环境和生物系统中的进一步应用。
