Over the years, engineering of more sensitive and specific enzymes, have led to the development of small, portable instrumentations for rapid drug testing.

• The problem: Chemotherapeutic drugs have very narrow therapeutic indices and highly variable pharmacokinetics, causing multiple side-effects and low efficacy.
• The solution: A Point-of-care biosensor allows the direct monitoring of drug concentration in serum, affording real time adjustment of the dosage according to the characteristics of the individual being treated (personalized treatment).
