摘要:

为解决传统有创检测血糖的问题,文中对近红外光谱无创血糖检测技术进行了研究。使用ABB公司的TALYS ASP531近红外光谱仪测得葡萄糖溶液的光谱,建模波段选取5 500~6 500 cm -1,使用偏最小二乘法建立光谱数据与对应浓度之间的校正模型。实验结果表明,校正模型的决定系数达到了0.983 99,校正均方根偏差为1.023 26 mmol·L -1,误差分布为-1.3~1.7 mmol·L -1,证明了近红外无创检测人体血糖浓度的可行性,为近红外血糖检测的研究提供了可靠的依据。

Abstract:

In order to solve the problem of traditional invasive blood glucose detection, the noninvasive blood glucose detection technology by near infrared spectroscopy was studied. The near infrared spectra of glucose solution were measured by TALYS ASP531 near infrared spectrometer of ABB Company. The selected modeling band was 5500~6500 cm -1 and the calibration model between spectral data and corresponding concentration was established by partial least squares method. According to the experimental results, the determination coefficient of the calibration model reached 0.98399, the root mean square deviation was 1.023 26 mmol·L -1, and the error distribution was -1.3~1.7 mmol·L -1. The results demonstrated the feasibility of non-invasive detection of human blood glucose concentration by near-infrared, and provided a reliable basis for the study of near-infrared blood glucose detection.
