اسلاید 3: 1IntroductionIdea of using Nanotechnology in medicine:Nanorobots in human body1999‪Robert A. Freitas JrNanomedicine:Use of nanotechnology to bring about improvements in healthcareBy modified physical/chemical/biological properties of nano-scale materialsMany biological mechanisms in human body also occur at nano-scale 1960 Zurich2007European Foundation for Clinical Nanomedicine (Switzerland)

اسلاید 4: 2Aim of nanomedicine Of all human biological systemsFrom molecular level Using engineered devices & nanostructures

اسلاید 5: 3Nano-scaleSome physical laws → Different at Nano-scale↓Size ↑Surface/volume ratio Nanoparticles:huge surfacesuitable for chemical interactions with biomolecules↓biochemical reaction time Analytical devices → faster & more sensitiveSmaller devices:Lower invasivenessPossible to implanted within body.Small size of biological sample for measurementViscosity = more effective at nanoscale↑interaction with capillary wallsNanofluidics: more complex than microfluidics.

اسلاید 6: 4Nano scale1nm = 1/106 mmA single human hair = 80,000 nm Typical protein size = 3-10 nmRed blood cells = 6000-8000 nmNanoparticulate systems:Size ranging from a few nanometers (micelles)To several hundreds of nanometers (liposomes)
