用逐层（LbL）方法将四（4-磺基苯基）卟啉（TSPP）和聚（烯丙基胺盐酸盐）（PAH）双层膜修饰的倏逝波光纤传感器用于测量人体皮肤散发的气体。在卟啉基薄膜的透射光谱中的不同波长处的光强度变化由人体皮肤气体引起，并作为传感器响应测量。相对湿度的影响，这可能是一个主要的干扰传感器的响应，是显着不同的皮肤散发的影响相比。当前光学传感器系统的响应可以被认为是复合传感器阵列，其中不同的光学波长充当对特定挥发性化合物具有选择性响应的通道。从传感器系统获得的数据进行了分析，通过主成分分析（PCA）。这种方法能够区分不同人的皮肤气味和他们饮酒后改变的生理状况。
An evanescent-wave optical fibre sensor modified with tetrakis(4-sulfophenyl)porphine (TSPP) and poly(allylamine hydrochloride) (PAH) bilayers using an layer-by-layer (LbL) approach was tested to measure the gas emitted from human skin. Optical intensity changes at different wavelengths in the transmission spectrum of the porphyrin-based film were induced by the human skin gas and measured as sensor response. Influence of relative humidity, which can be a major interference to sensor response, was significantly different when compared to the influence of skin emanations. Responses of the current optical sensor system could be considered as composite sensor array, where different optical wavelengths act as channels that have selective response to specific volatile compounds. Data obtained from the sensor system was analyzed through principal component analysis (PCA). This approach enabled to distinguish skin odors of different people and their altered physiological conditions after alcohol consumption.
