Abstract

The invention belongs to the field of medical detection, and particularly relates to a portable biological tissue detection device based on a space deviation Raman spectrum technology. The biologicaltissue detection device comprises a computer, a detection controller, a laser, a spectrometer, a three-freedom-degree mechanical arm, an SORS detection head, a detection platform and a sealed sample chamber. An SORS technology is used; a sample to be tested is sealed; during the storage in dark places, equipment can be directly used for detecting the Raman spectrum, so that the detection is performed in a targeted way; the SORS technology and an SERS technology are used in a combined way; the defect of lower SORS detection biological sample signals is overcome; meanwhile, the problem that theSERS detection sample can only be used for detecting the expression information is solved; a novel SORS detection head is designed; the detection head has the advantages that the detection sensitivityis high; the control is easy; the displacement control precision is high; the influence by the precision of the step motor is avoided. The novel biological sample storage device is designed; the sample can be stored for a long time; the SORS signal detection can be detected at any time.

Description

technical field [0001] The invention belongs to the field of medical detection, and relates to a biological tissue detection device, in particular to a portable biological tissue detection device based on space offset Raman spectroscopy technology. Background technique [0002] In modern medical testing, biological tissue testing is an important way for medical diagnosis. Since changes in biological tissue will lead to changes in its internal tissue composition, by detecting biological tissue, obtaining information about its composition, and comparing it with healthy and diseased tissue composition information, the health status of the organism can be further determined. [0003] Raman spectroscopy is a useful tool for analyzing molecular structure. The characteristic peak position, intensity and line width of Raman spectrum can provide information on molecular vibration and rotation, reflecting different chemical bonds or functional groups. As a non-destructive, non-conta...
