The goal of this study is to exploit the phase change in vanadium dioxide (VO₂) for optical sensing. Infrared (IR) sensing is of paramount interest for next-generation Internet of Things (IoT) devices. Phase change materials (PCMs) are expected to enable low-energy consumption sensors, ...

Cancer cells have an increased sensitivity to heat compared to healthy cells; at 42°C cancer cells are destroyed while normal cells can survive up to 47°C. Thus hyperthermia-based approaches that target specific spatial locations and simultaneously provide controlled thermal exposure ... En savoir plus

Our group developed an experimental millimetric capsule intended to release chemicals or drugs. The delivery mechanism of such device relies on the thermal expansion of carbon-elastomer composites which deform upon irradiation of light supplied by a Laser diode through an optical fiber. ...

Photothermal deflection spectroscopy (PDS) relies on the angular displacement of a probe beam through a fluid with varying index of refraction. The precise angular displacement of the probe beam is dependent on the entire index of refraction field, which is in turn dependent on fluid ... En savoir plus

Microfluidic systems traditionally rely on fixed physical barriers to manipulate fluids and particles. While effective, these static structures lack the flexibility required for dynamic or multifunctional applications. In this work, recently published in Nature Photonics [1], we present ...

Graphene, as a two-dimensional material with exceptional physical and chemical properties, exhibits highly tunable optical absorption within the visible spectrum. Its absorption is sensitive to polarization, the number of layers, and incident angles, making it an ideal candidate for ... En savoir plus

Pancreatic cancer is one of the deadliest cancers, with a 7% survival rate at five years from diagnosis. The limited number of treatment options for patients who are diagnosed with late-stage disease is a major contributor to this problem. Therapeutic modalities such as radiofrequency ...

Laser-induced photovoltage in ferromagnetic thin films is often explained by magneto-thermoelectric effects such as the anomalous Nernst effect (ANE). ANE appears when thermal gradients interact with magnetization. While power loss in flat films can be estimated analytically, numerical ... En savoir plus

Pleural photodynamic therapy (PDT) represents a promising treatment approach for malignant pleural mesothelioma. However, optimizing treatment efficacy requires accurate prediction of reactive oxygen species ([ROS]rx) distribution, which is challenging due to complex cavity geometries ... En savoir plus

Laser immunotherapy (LIT) was developed to treat late-stage, metastatic cancers through local laser irradiation and immunological stimulation. In ILIT, the photothermal effect induces immune responses by destroying and interrupting tumor cells through temperature elevation in target ... En savoir plus
