Improvement of the contrast of photoplethysmographic measurements for the monitoring of physiological parameters

Photoplethysmography (PPG) is a non-invasive optical technique for detecting temporal variations in blood volume in tissues. PPG is used to monitor physiological parameters such as heart rate, pulse oximetry and blood pressure. PPG is a widely used method in physiological measurement systems, whether for consumer connected objects (smart watches, smartphones) or medical systems (oximeters). Even […] >>

Magnetically actuated artificial membranes for biotechnology

New biocompatible magneto-elastic membranes have recently been developed at SPINTEC, based on the integration of magnetic microparticles previously investigated in biological studies [1]. Our earlier studies aimed at cancer cells destruction, through the low frequency magneto-mechanical vibrations of the particles dispersed among the cells [2). Here, on the contrary, magnetic particles are patterned in an […] >>

Engineered BiomimEtic platforms to analyse the molecular and cellular role of Heparan Sulfate on bone morphogenetic protein 2

CONTEXTE The industrial development of biomaterials for bone tissue regeneration is steadily increasing due to socio-economical need for bone repair therapies especially caused by the aging of the population and improvement of the quality of life. A boost of bone repair can be achieved using potent osteoinductive proteins, named bone morphogenetic proteins (BMPs). In Europe, […] >>
