Mobile oral heath technologies based on saliva.

In this review we have highlighted a few innovative microfluidic analytical technologies with mobile phone image processing tools for various bio-chemical tests performed using salivary biomarkers. Saliva-based assays for mobile monitoring with a smartphone sensor provide an excellent analytical technique which can be simple to perform. We describe several examples from the literature, utilizing different modalities of analysis, applied to several different applications of mobile health monitoring: cortisol monitoring, infectious disease testing, and drugs of abuse.
