A New Nano Device for Blood Analysis

Published Date : Oct 16, 2014

A new sensor has been developed by a team of researchers at the Center for Scientific Research and Higher Education of Ensenada, Baja California (CICESE). This research has been conducted in the area of Nano-Optics. This sensor is based on the properties of light to carry out blood analysis thereby, enabling the health specialists and physicians to get accurate and exact information. The development of this sensor has been allowed to obtain a patent and its publication has been permitted in several journals. 

The leader of Nano-optics at CICESE has explained that the main challenge in the area of health is to come up with healing techniques that quick and have immediate impact. Simple assessment techniques like CBC require many hours and sometimes even several days. Another problem being faced is the issue of the absence of personalized diagnosis. This sensor not only provides accurate information but it can also be used at home in the future.

The researchers are working on two main aspects, the first being, the development of a sensor that uses the principles of optics at a nanoscale and the second, how the fluid can be inserted in these dimensions. The basic challenge is to create a portable lab on a chip that has the capacity to make individualized measurements.

According to a physicist, the ITESM researchers were interested in this sensor and applied it into the development. 

The device involves the application of structures that blend a liquid in motion containing the sample to be analyzed; so that more of it can reach the place where the real measure by sensing is taking place. 

Interestingly, such sensors were developed in the sixties and are not a new technology. However, this needs to be exploited. A scientist at CICESE has stated that the main contribution of the research team has been the realization of its potential and the incorporation of the current methods that include the principles of nanotechnology and optics.
