Biosensors For the Measurement of C-Terminal Telopeptide of Type I Collagen (CTX-I)

Nasrin Afsarimanesh, Subhas C Mukhopadhyay and Marlena Kruger

In the last few years, research on the use of biochemical markers of bone turnover has greatly improved. Among the several available bone turnover markers, monitoring serum C-terminal cross-linked telopeptides is one of the most accurate one. Manual and automated immunoassays are available for the measurement of CTX, which show high analytical performance. However, they are very expensive, time-consuming and require technical experts to perform the CTX assay. Different research groups have proposed novel immunosensing methods to detect CTX biomarker. It is a hope that the development of a rapid and inexpensive point-of-care device can aid in monitoring the bone metabolism more frequently, which can be helpful in indicating the early stages of bone loss.
