Sensitive acid sensor controls insulin production

11 agosto 2014

Many human metabolic functions only run smoothly if the acid level in the body remains neutral and stable. For humans, normal blood pH values lie between 7.35 and 7.45. By way of comparison, an empty stomach is extremely acidic, with a pH value of 1.5. A team of bioengineers have now developed a new implantable molecular device composed of two modules: a sensor that constantly measures blood pH and a gene feedback mechanism that produces the necessary amount of insulin.
