Optical Biopsy: detecting cancer and pre-cancer with elastic light-scattering spectroscopy

Departments of Biomedical Engineering, Electrical & Computer Engineering, Physics, School of Medicine

Optical spectroscopy, mediated by fiberoptic probes, can be used to perform noninvasive, or minimally-invasive, real-time assessment of tissue pathology in-situ.  The method of elastic-scattering spectroscopy (ESS) is sensitive to the sub-cellular architectural changes, such as nuclear grade and nuclear to cytoplasm ratio, mitochondrial size and density, etc., which correlate with features used by pathologists when performing histological assessment to detect disease.  The optical physics of the ESS method will be explained, elucidating how the method senses the cellular morphology changes without actually imaging the microscopic structure.  Clinical demonstrations of ESS have been conducted in a variety of organ sites, with promising results; larger-scale clinical studies are now ongoing.

Dr. Carlos Ríos

Reconfigurable integrated photonics enabled by phase-change materials: from optical switches to neuromorphic computing
Department of Materials Science and Engineering, Massachusetts Institute of Technology, Cambridge,

Optical phase change materials (O-PCMs) are a unique class of materials which exhibit extraordinarily
large optical property change when switching between the amorphous and the crystalline solid-state phases.
These materials, exemplified by Mott insulators such as VO2 and chalcogenide compounds such as
Ge2Sb2Te5, have been exploited for a plethora of emerging photonic applications. These traditional phase change materials, however, generally suffer from large optical losses even in their dielectric states, which fundamentally limits the performance of optical devices. In this talk, I will briefly discuss the state-of-theart of integrated photonic devices enabled by O-PCMs, their potential, and technological challenges. In particular, I will focus on the current efforts towards developing O-PCMs with unprecedented broadband low-loss and the integration of such materials in novel photonic systems, such as non-volatile multilevel memories, neuromorphic optical computing systems, switches, and routers towards a reconfigurable optical chip.

Modified surfaces and nanostructured materials for biomedical applications: Applied Plasma Physics and Scientific Instrumentation helping to solve problems for Materials Science.

Modified and coated surfaces is subject of a wide research and commercial application in the biomedical area, especially in calcium phosphate (CaP) thin coatings and surface functionalization of metallic implants. Among others, the magnetron sputtering (MS) and the Pulsed laser deposition (PLD) are some of many techniques of plasma assisted physical vapor deposition for the production of nanostructured and biocompatible thin coatings. The aim of those modified surfaces is mainly to improve the adhesion between materials surface and biological media, as well to promote osteoinduction. To avoid several biological setbacks in orthopedic and ontological procedures, stoichiometric, crystalline and stable CaP coatings should be deposited at room temperature. For that purpose, new MS designs and instrumentation have been developed to promote strong magnetic field confinement. The plasma characterization of those new MS systems have shown the influence of the lower and high hybrid resonance waves from the plasma ions and electrons in localized magnetic field gradients.  Those resonance waves seem to increase the energy delivered to the sputtered ions, helping the CaP film growing, crystallization and stoichiometry.
