MNPMolecular and Nano physics
1 nanometre 10-9 meters 0.000000001 meters
2
Research using nano physics

• Biological physics applying physical testing to
  biological materials / functions
• Measure the elasticity of the protein involved in
  blood clots, fibrinogen.

3
Lipid bilayers

• Material of cell membrane
• Also forms Exo-skeleton of bacteria
• Study how effective an antibiotic is.
• Using XPS (X ray Photoelectron Spectroscopy ) to
  measure strength of chemical bond of an
  antibiotic in the layer.

Hydrophilic
Hydrophobic
4
Fluorescent dots

• Fluorescent material
• Tagging
• Diffusion time
• Time for a antibiotic to disrupt the layer.

Light excites the material

5
Imaging at the nano scale

• Think of a needle
• 1 Atom wide at the tip
• Run this across a surface
• Imaging increases the understanding of how these
  systems work

Conclusion

• Reasons for MNP
• Research into effectiveness of antibiotics which
  are used in medical treatment
