  1. Smarter Sensors: in Crop Production and Protection

    17 Mar 2015 | | Contributor(s):: Ali Shakouri, Babak Ziaie

  2. [Illinois] How to Break the "Fundamental" Limits of Nanobiosensing

    07 Apr 2014 | | Contributor(s):: Muhammad A. Alam

    As the future of Moore’s law of transistor scaling appears uncertain, electronics is being reinvented by broadening the focus to other areas including macroelectronics (electronics of large, possibly flexible and transparent displays), bioelectronics (e.g., nanobio sensors for genomics,...

  3. [Illinois] ECE 416 Impedance Based Sensors II

    10 Apr 2013 | | Contributor(s):: Brian Cunningham

               In this lecture, we start off with a light review of the nanopore sequencing method which is based upon having a carefully bioengineered pore that can induce different changes in charge blockages as different base pairs go through...

  4. [Illinois] ECE 416 Lumerical Optical Simulation

    10 Apr 2013 | | Contributor(s):: Brian Cunningham

               In this lecture, we looked at lumerical optical simulation. The motivation to pursue this topic is because there is now software available that allows us to conduct simulations to visualize Electromagnetic field locations, to...

  5. [Illinois] ECE 416 Fluorescence I

    10 Apr 2013 | | Contributor(s):: Brian Cunningham

               In this lecture, we discussed Fluorescence molecules and how they can be used for detection of other molecules. The molecules are considered to have high energy states, which helps them with their detection. The photons discussed...

  6. [Illinois] ECE 416 Fluorescence II

    10 Apr 2013 | | Contributor(s):: Brian Cunningham

               In this lecture, we start with a revision of the common organic dyes and the photostability and quenching concepts. Quenching is then discussed in more detail and the difference between self-quenching and external quenching....

  7. [Illinois] ECE 416 Optical Sensors II

    27 Mar 2013 | | Contributor(s):: Brian Cunningham

               In this lecture, there is a review of the previous lecture of SPR Sensors along with Reflection Interference Spectroscopy. We learned that as we go to longer wavelengths, the refractive index is more constant. Then, we looked at...

  8. [Illinois] ECE 416 Optical Sensors III

    27 Mar 2013 | | Contributor(s):: Brian Cunningham

               In this lecture, we finished our discussion over optical sensors. We started with discussing a photon moving between 2 mirrors with 100% efficiency, the photon gets to "sample" the media between the mirrors with no loss. This was...

  9. [Illinois] ECE 416 Impedance Based Sensors I

    27 Mar 2013 | | Contributor(s):: Brian Cunningham

               In this lecture, we were introduced to the concept of a new sensor called the impedance-based Biosensor. Biomolecules are originally charged and therefore there is a need to determine the charge of the molecule before using it on a...

  10. [Illinois] ECE 416 SPR Sensors I

    27 Feb 2013 | | Contributor(s):: Brian Cunningham

               This lecture was an introduction to Surface Plasmon Resonance (SPR) Sensors. It started out with an explanation of Coulomb's Law for the force between two charges. This lead to the concept of the electric field and with an applied...

    17 May 2010 | | Contributor(s):: Brian Cunningham

    Planar photonic crystals have been used as the basis of many biological sensing devices. Here, we successfully demonstrated that the combination of a photonic crystal structure and a dielectric nanorod coating prepared by the glancing angle deposition technique can lead to significant increases...
