Nanometric platforms for biomedicine

Historical overview

From the grounds of a solid experience in molecular magnetic materials, some researchers in the M4 group shifted his interest to the emerging field of nanotechnology some 30 years ago. The first efforts were dedicated to the development of synthetic procedures for the control of crystal phase, size and shape of iron oxide nanoparticles that crystallized in a new patented method based on the use of polymers as precipitating matrix.

Soon it became evident that the most promising applications of these nanoparticles were in the biomedical field and the focus was set on these applications. The attention of the group was specially directed to hyperthermia therapy and, later on, a new line of research emerge: nanothermometry; as this is an essential tool for the advance in this field.

At present, the aims of the group are: 1) the development of multi-therapeutic tools for cancer including hyperthermia; 2) the development of luminescence nanothermometers with high spatial and time resolution; 3) the use of these nanothermometers for monitoring intracellular phenomena involving thermal processes.

Present Goals

2D temperature imaging with high spatial and time resolution.

The group designs and produce temperature sensitive luminescence nanoprobes, and builds instruments for the detection of luminescence emission from this probe and conversion into 2D temperature imaging of the object of observation. The functional molecular groups of the probes are lanthanide complexes. The signal of the probes is transformed in absolute temperature data

Enhanced Hyperthermia therapy.

Based on a local application of small amounts of heat localized in certain intracellular sites such as mitochondria. It is expected that the generation of high enough temperature gradients on these sites could induce cell apoptosis, thus using an amount of heat considerable lower than that employed on actual hyperthermia treatment, which are based on whole tumour heating
