Background
Compared with the traditional liquid biopsy material blood, the saliva sample contains the same proteins (such as enzymes, hormones, antibodies, growth factors and the like) as the saliva sample, and the saliva also contains genetic information such as DNA, RNA and the like. The saliva biopsy has the unique advantages of more convenient material taking, complete non-wound, blood-borne infection avoidance and the like. More and more evidence shows that saliva can be used for detecting head and neck or oral diseases close to the anatomical position of the saliva, and can also be used for detecting systemic diseases of the whole body, and the saliva biopsy has the application prospect without the limitation of the spatial position. Currently, saliva detection is a common detection item in medical institutions such as hospitals, and saliva is increasingly used for clinical basic research.
The currently common saliva collection method is spitting method, i.e. the subject spits saliva directly into a saliva collection device through a funnel-like device, but some viscous saliva is not easy to flow down, which results in large loss of the sampling method, and in addition, the saliva collected in this way may contain some impurities such as food residues, etc., further affecting the downstream detection or research process.
