Identifying mineral decrement with bone injury by quantifying osteocalcin on current-volt sensor.Osteoporosis, a bone disease is caused by the deterioration of bone and shows an enhanced risk of bone fracture and decreasing bone mineral density.  This research is focused to develop a point-of-care system to identify osteocalcin on current-volt sensor, which helps to diagnose the bone metabolism and prognostics.
