Edward M. Purcell Distinguished Professor of Physics

Professor Nolte is the Edward M. Purcell Distinguished Professor of Physics. Edward Mills Purcell (1912 - 1997) received his undergraduate BS from Purdue University in 1933 where he was encouraged by Prof. Lark-Horowitz to do undergraduate research in physics under Profs. Walerstein and Yearian. Purcell was awarded the 1952 Nobel Prize in Physics for his discovery of nuclear magnetic resonance, the physical basis of MRI imaging. In 1977 he published a landmark paper "Life at Low Reynolds Number" that applied principles of hydrodynamics to biological systems. He was awarded, with Howard Berg, the Max Delbrück Prize for biophysics of the American Physical Society in 1984. He made a lasting mark on physics education with his relativistic approach to teaching electricity and magnetism in his 1965 Berkeley Physics Course textbook.

The Coherent Optics and Laser Interferometry Group, directed by Professor David D. Nolte uses laser interferometry to study intracellular dynamics. We have a special focus on the physics of partial coherence combined with the propagation of light through biological tissues. We developed Biodynamic Imaging (BDI) and Tissue dynamics spectroscopy (TDS), based on Doppler light scattering from intracellular motions, in a physics-based approach to cancer science.

 

Research Positions

Research positions are open for graduate research assistantships (RAs) and for undergraduates pursuing a senior thesis. Experimental research focuses on the interaction of light and lasers with living biological systems. Computation research focuses on the application of Twin and Triplet artificial neural networks for highly variable feature classification. Theoretical research focuses on photon Monte-Carlo approaches to coherent light propagation in random dynamic media.

 

Holographic Biodynamic Imaging


VolumeMotionSmall.jpgVolumetric imaging of cellular motion in a tumor spheroid. Full size

Laser fields propagating through scattering tissue retain an exponentially decaying coherence that can write holographic gratings on a holographic medium. The first volumetric holograms of living tissue were made by our group at Purdue University in 2002 using ultra-sensitive dynamic holographic film called photorefractive quantum well (PRQW) devices. Digital holography, using CCD cameras, provides similar advantages for holographic optical coherence imaging (OCI). In biomedical imaging applications, intracellular motility, recorded as shimmering holograms, acts as a novel imaging contrast agent. Recent interest is on the action of anti-mitotic cancer drugs on tissue. | Cellular motility as a novel contrast agent in digital holography of tissue

The recent development of Tissue Dynamics Spectroscopy (TDS) opens up new opportunities to study the functional influence of new drug compounds on living tissue. Tissue Dynamics Spectroscopy performs label-free non-invasive measurements of the intracellular dynamics inside living tissue and evaluates how these dynamics are altered by applied drugs.  The need that TDS addresses is its ability to bridge the gap that has persisted in the drug-discovery pipeline between high-throughput 2D monolayer cultures and preclinical animal models (where drug failures are much more expensive). Three-dimensional tissue-based drug screens (for therapeutic efficacy and specificity) are needed to bridge this gap because 3D tissues are more representative of cellular and tissue responses to applied drugs than those in 2D monolayer culture.  Currently there are no volumetric imaging modalities that capture drug response without labels deep in tissue far from surface effects. The response of tissue to an applied drug is represented as a drug-response spectrogram.  Every different type of drug has a different spectrogram fingerprint.  Different spectrogram features are related to different mechanisms of action of the drug, for instance monitoring cell metabolism or cytoskeletal integrity, or apoptotic response. 

The stage in early drug discovery that comes after high-throughput screening is called “hit confirmation and expansion”.  At this stage in the drug development pipeline, screens are needed to test “hits” for therapeutic efficacy (does it modify a selected target?) and specificity (does it only affect a selected target?).  Target response is either molecular (pathway) or physiological (phenotypic profile).  Tissue dynamics spectroscopy enters the marketplace as a new screening technology for early drug discovery.  The field of use of TDS is hit confirmation and expansion.  The target is high-content phenotypic profiling of physiological response to drug candidates.

The BioCD

The BioCD performs molecular diagnostics in the form of a compact disc. The BioCD, invented in the Adaptive Optics and Biophotonics group at Purdue University, combines the simplicity of spinning-disc interferometry (SDI) with the power of antibodies to detect disease. A conventional compact disc has 5 billion diffraction-limited pits encoding digital information. The motivation behind the BioCD is to turn a disc into 5 billion micro-test-tubes to test for every type of blood protein in a few drops of blood. The science of molecular interferometry combines the physics of laser coherence, quantum optics, light-matter interactions, and surface science, with molecular biology and biomedical diagnostics. | Tutorial on Molecular Interferometry |

 

 

Microfluidics

Following the example of integrated electronic circuits, the "lab-on-a-chip" uses micro-fabrication to create microfluidic systems that transport liquid samples through reaction and analysis chambers for biochemical assays. We are studying the fundamental physics of fluids in micron and nanometer-scale systems. The unstable fingering of invading phases in 2D random systems, and thermodynamic properties of liquids in contact with other liquids or solids, leads to strong hysteretic relationships between saturation and capillary pressure that has eluded clear theoretical explanation. Moving into three dimensions is being pursued by building porous microsystems using two-photon polymerization (2PP) laser micromachining.
