Compounds, systems, and methods are provided for the design and assembly of a non-invasive, analyte sensing dressing. The dressing includes a sensor and a matrix. The sensor is capable of detecting analytes such as molecular oxygen, carbon dioxide, nitric oxides, dissolved analytes in plasma, and hydrogen ions. The device emits a detectable signal when the sensor is excited in the presence of the analyte. In one version of the dressing, the sensor includes a meso-unsubstituted metallated porphyrin that is sensitive towards oxygen. The metallated porphyrin can be excited when illuminated at a first wavelength, followed by emission of phosphorescence at a second wavelength whose intensity can be used as an indicator for oxygen concentration. The porphyrin can have the Formula (II):
wherein R1 includes a moiety selected from the group consisting of alkynl groups, triazolyl groups, alkylglutamate groups, and a pair of alkylglutamate groups.
为设计和组装非侵入式分析物传感敷料提供了化合物、系统和方法。敷料包括传感器和基质。传感器能够检测分析物,如分子氧、二氧化碳、一氧化氮、等离子体中溶解的分析物和氢离子。当传感器在被分析物存在的情况下被激发时,该装置会发出可检测的信号。在一种敷料中,传感器包括对氧敏感的中未取代金属化卟啉。金属化卟啉在第一波长照射时会被激发,然后在第二波长发射磷光,其强度可用作氧气浓度的指示剂。卟啉的化学式为 (II):
其中 R1 包括选自由炔基、三唑基、烷基谷氨酸基和一对烷基谷氨酸基组成的组的分子。
