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!!
