Chapter 1 Review Question Answers

Following are selected answers to the review questions at the end of Chapter 1 in Understanding Nanomedicine:  An Introductory Textbook by Rob Burgess.

1.  The nanoscale ranges from 0.1nm to 1mm and is characterized at the low end by an atom and the high end by a grain of sand.  Other examples of objects which can be measured on the nanoscale include the diameter of DNA (1nm), the diameter of a carbon nanotube (10nm) and a transistor (35nm).


4.  The concentration of surfactant monomers above which spontaneous micelle formation occurs. 


C = CMC, (d3F/dCt3) = 0

F = a[micelle] + b[monomer]: function of surfactant solution

Ct: total concentration



7.  A top-down approach to manufacturing involves the use microfabrication machinery to externally control the atomically or molecularly precise synthesis of a desired material.  Bottom-up approaches to nanoscale synthesis are focused on the assembly of a material, object or device from individual components.  Said assembly often, but not always, involves the concept of self-assembly, whereby a molecule, for example, can wrap upon itself based on inherent chemical and physical properties to form a 2-dimensional or 3-dimensional shape.



10.  Cancer, tissue engineering, clinical neuroscience, surgery, stem cell applications and diagnostics.
