Intro to Biophysics Flashcards
What is Biophysics?
It is the study of physical phenomena & physical processes in living things on scales spanning molecules, cells, tissues & organisms.
What is Scale spanning molecules?
- It is a type of research
What is the long term goal of scale spanning molecules research?
it is to develop a molecular microscope for defining cellular systems w/ scales spanning all the way from the dimension of a cell to the atomic resolution of molecules.
Who are Biophysicists?
Are people that use principles & methods of physics to understand biology.
Why are Biophysicists important?
- work to develop methods to overcome diseases.
- Eradicate Global hunger
- Produce renewable source of energy
- Design cutting edge technologies
- Solves countless scientific mysteries
Application of Biophysics?
- Data Analysis- solved structure of DNA in 1953. allows for the reading of DNA sequences
- Computer Modelling- uses methods to see & manipulate shapes & structures of proteins, viruses & other complex molecules.
- Cellular communication/molecular motion- study how hormones move around & communicate w/ cells.
- Application in Neuroscience- building computer models called neural networks to model how brain & nervous sys. work.
- Bioengineering, Nanotechnology & Biomaterials- crucial to understanding biomechanics.
- Imaging- developed sophisticated diagnostic technology.
- Medical Applications- development of lifesaving treatments & devices
What are the 3 types of imaging used in diagnostics?
- Magnetic resonance imaging (MRI)
> uses a magnetic field to see organs & tissues. - Computerized Tomography (CT scan)
> uses x-ray images to see bones, blood vessels & soft tissues - Position Emission Tomography (PET scan)
> uses a radioactive drug (tracer) to see metabolic activities.
Which type of Imaging diagnostic technique is the best?
PET scan (Positron Emission Tomography)
What are some professions that Biophysicists have?
- Teaching
- Research in Biology
- Teach Physics
- Engineer
