  • Introduction Name: Samuel Karas Topic: Magnetic Resonance Force Microscopy (MFRM)Image take with MRFM
  • What is it in a nutshell?MRI + Magnification times one million = MFRM
  • This is a very barebones explanationSo what really is it?
  • It is actual a combination of two modern technologiesThe MRIAnd Atomic Force MicroscopyTo better understand MRFM, we must first look at these two technologies
  • MRI (Magnetic Resonance Imaging)Non-invasive imaging systemUnlike X-ray it utilizes a magnetic field to produce the picturesIt tracks the oscillations of the protons in order to create a picture.
  • Atomic Force MicroscopyThe laser shines on the object that the image is being created of.The light reflects off the object and cantilever to a position detector.This is what creates the image
  • The concept was created by Dr. John A. Sidles in 1991.He wanted a machine to create images of tiny particlesQuote
  • How it worksEach of these parts plays a integral part in the machine.I’ll go into more detail in a second.
  • The specimen is placed on the cantilever, because of the way this machine works, it does not need to be crystallized in any way.This magnet is used as a constant.The vibrations are picked up by the laser which is what creates the image.This final magnet spins which which causes the vibration of the cantilever
  • The equationF= Forcem = spin magnetization – The coiled magnetB= permanent magnet – The spinning magnet
  • It can view the structure of dnaIt can view proteins previously unable to be viewedIt can also view biological items that for some reason cannot be crystalized
  • It has the ability to view subsurface images, unlike a Scanning Electron Microscope.It also has the ability view things at the atomic level.THE END!!
