With recent advancements in micro-fabrication and nano-fabrication techniques as well as
advancements in the photonics industry, there is now the potential to develop less invasive
portable sensors for monitoring micronutrients and other substances used to assess overall
health. There have been many technology innovations in the central laboratory for these
substances for overall health status but the primary motivation for the research and
development of a portable field instrument has come from a diabetic patient and market …
