General guidelines

  • This is a group report — one paper per group.
  • Use of bulleted lists and tables is highly encouraged; long paragraphs are not necessary.
  • Include a summary of the algorithm used for all calculations and analyses performed, including MATLAB (or other language) code. Put the code in an appendix.
  • Don’t forget scale bars on images, titles, units, nd labels on plots.
  • The report should be in PDF format, submitted electronically in advance of the deadline to Stellar

Section 1: Microscope Documentation and Design

  • Block diagram of the microscope, including all optical elements and relevant distances. It is unnecessary to document the details of the mechanical construction.
  • Design calculations and considerations
  • Photograph of your setup (optional, but nice)

Section 2: Microscope Characterization

  • Basic optics: include a table with the following values for the 10X, 40X, and 100X objectives:
    • Theoretical resolution
    • Actual magnification by multiple measures (Air Force Target, Ronchi Ruling, microspheres)1
    • Actual field of view (FOV)1
    • Example pictures from each objective (fluorescence mode)
  • Estimate of actual resolution of the 40X Objective
    • Images used for computation (with fit, if you like – see plotgaussfit command)
    • Estimate of FWHM by Gaussian fitting
    • Bullet point outline of data analysis methodology
    • Comments on estimated versus theoretical value
  • Stability
    • X-Y plots of sum and difference tracks for “stationary” particles.
    • MSD versus time interval for sum and difference tracks
    • Bullet point outline of data analysis methodology
    • Comments on observed vs. expected data trend

Section 3: Fluorescence Microscopy

  • Unprocessed Images of fluorescent bead and onion samples and associated reference images
  • Corrected images
  • Image or surface plot (see surf command in Matlab) of correction applied
  • Histograms of original and corrected images
  • Segmented onion image
  • Corrected, fluorescent image overlayed on bright field onion image
  • Bullet point outline of image processing methodology

Section 4: Particle Tracking

  • X-Y plots of tracks for all 5 samples
  • MSD versus time interval plots for 5 samples
  • Estimate of diffusion coefficient and solvent viscosity for each sample
  • Comments on results
  • Bullet point outline of all calculation and data processing steps
