Mesoporous metal films can detect biomarkers with high sensitivity. Further coating the mesoporous metal with polymers enhances sensing selectivity by favoring specific biomarkers against other interferents. In the present study, we report the fabrication of a Nafion®-coated mesoporous Pd film to filtrate interferents present in sweat during non-invasive biosensing. By using a Nafion®-coated mesoporous Pd film, lactic acid, a metabolite present in sweat, can be successfully detected with high sensitivity.
介孔金属薄膜能够高灵敏度地检测生物标志物。用聚合物进一步包覆介孔金属,通过优先选择特定生物标志物而排斥其他干扰物来提高传感选择性。在本研究中,我们报道了一种用于在无创生物传感过程中过滤汗液中存在的干扰物的涂覆有Nafion®的介孔钯薄膜的制备方法。通过使用涂覆有Nafion®的介孔钯薄膜,能够成功地高灵敏度检测汗液中存在的代谢物乳酸。
