Diffuse optical methods for the diagnosis and imaging of biological tissues (Infotech Lecture course)

Diffuse optical methods constitute a unique and flexible tool to get a non-invasive insight into a number of organs. They offer the possibility to characterize or image (2D,3D) and quantify elementary constituents of biological tissues such as blood (oxy- and deoxyhemoglobin), fat, water, collagen … By accessing to the composition of the tissues, physicians can diagnose a pathology (skin cancer for example) and monitor its evolution.

In this lecture, after an introduction on basics of tissue optics, I’ll briefly formulate the main governing equations of light propagation through biological tissues (forward problem), principles of resolution of inverse problems, and give an overview of some of these techniques (Diffuse Reflectance Spectroscopy, Diffuse Optical Tomography, Polarization gating, Photoacoustics).

Photon mayhem: using light for structural and functional assessment of biological tissues (SPIE Invited Lecture)

Medicinal photonics (biophotonics) includes a variety of therapeutic (effects of light on tissue) and diagnostic (effects of tissue on light) applications. In this talk, the latter category will be highlighted, with emphasis on methods actively investigated in our laboratory – optical coherence tomography for microvascular imaging and tissue polarimetry for anisotropy monitoring. Both of these approaches rely on the wave nature of light (coherence and polarization, respectively) and offer unique biophysical information on tissue structure, composition, and function.

Photocatalytic mitigation of organic contaminants and human pathogens

Semiconducting nanomaterials and their doped as well as hybrid derivatives are the frontiers in future photocatalytic applications. Using smart design strategies one may construct their films and coatings on surfaces of arbitrary shape but also can apply as colloidal dispersions to facilitate photocatalytic conversion of simple chemical substances as well as complex biomaterials and microorganisms in a versatile manner. In the talk, we address the core mechanisms responsible for efficient photocatalytic reactions, and demonstrate several examples of practical applications including oxidation of organic dyes to clean surfaces, reforming of alcohols to mitigate those in polluted waters while simultaneously producing hydrogen, and show eradication of drug resistant bacteria.

Visible light communications: Opportunities in the medical ICT field

In this presentation, visible light communications (VLC) will be introduced and two highly promising applications will be discussed. First, the use of VLC as a secure and safe approach to provide wireless connectivity to the hospital of the future will be presented. The use of VLC techniques to transmit information through bio-tissues will also be discussed.
