    25 Sep 2010 | | Contributor(s):: Gabriel Popescu

    So far, we have discussed Fourier transformations involving one-dimensional functions. Of course, in studying imaging, the conceptmust be generalized to 2D and 3D functions. For example, diffraction and 2D image formation are treated efficiently via 2D Fouriertransforms, while light scattering...

    25 Sep 2010 | | Contributor(s):: Gabriel Popescu

    Often, experiments involve light beams. A light beam can be defined as a distribution of field that fulfills the approximation in Eq. 20,i.e. is characterized by a dominant wave vector component, k(z) >> k(x) , k(y) . A beam is, therefore, the spatial equivalent of quasimonochromaticlight, where...

  14. A Gentle Introduction to Nanotechnology and Nanoscience

    13 Feb 2006 | | Contributor(s):: Mark Ratner

    While the Greek root nano just means dwarf, the nanoscale has become a giant focus of contemporary science and technology. We will examine the fundamental issues underlying the excitement involved in nanoscale research - what, why and how. Specific topics include assembly, properties,...

  15. A New Terahertz Heterodyne Detector Based on Single-Walled Carbon Nanotubes

    27 Jul 2005 | | Contributor(s):: Sigfrid Yngvesson

    We present non-invasive methods for improving the sensitivity of label-free biosensors that offer the advantage of rapid and real-time detection but suffer from relatively low sensitivity. We present detection of cancer markers using the Quartz Crystal Microbalance and demonstrate that 2...

  16. A Novel Diagnostic Assay Based On Nanomechanics

    28 Jul 2005 | | Contributor(s):: Marko Dorrestijn

    Micro-fabricated silicon cantilevers arrays offer a novel label-free approach where ligand-receptor binding interactions occurring on the sensor generate nanomechanical signals like bending or a change in mass that is optically detected in-situ. We report the detection of multiple unlabelled...

  17. AFM Sample Preparation in Biology

    22 Mar 2011 | | Contributor(s):: Irene Revenko

    All biological samples are different, the key is to start with established recipes for similar samples, then adapt the procedures for a different one. We'll present guidelines for choosing a substrate, immobilizing the sample, choosing the proper cantilever, as well as tips and tricks optimize...
