Método Alternativo para la Detección de Lactato en Solución Acuosa Basado en la Fluorescencia de los Puntos de Carbono.

Project: Research Project

Project Details


Measuring L-lactate levels constitutes an important step in clinical diagnosis and sports medicine.

Currently, this procedure can be carried out through sensors based on electrochemical systems, demanding a high economic and environmental cost, in addition, robust infrastructure to locate this equipment in laboratories and the human talent necessary for it.

The present proposal aims to establish an alternative method for measuring the concentration of L-lactate, based on the fluorescence properties that carbon dots (PCs) have and the development of a system that, based on the use of computer vision, is possible to estimate this concentration, obtaining the possibility of having a low-cost and portable system.

Basically, two phases are proposed: a first based on the synthesis and characterization of carbon dots for the detection of L-lactate and the analysis of its optical properties; and a second phase that will be responsible for the development of a hardware-software integration, using computer vision techniques.

The objective is that, from images generated by the fluorescence generated under ultraviolet light stimulation of the PCs dispersed in an aqueous solution of L-lactate, the concentration of this analyte can be estimated.

Among the expected results is, mainly, a prototype system for the estimation of portable and low-cost L-lactate level concentration.
