52) (p. 92) Describe the reason why the modified DNA can serve as a scaffold for 1D arrays of metal ions. 53) (p. 95; first arrow) Read the sections marked with arrows carefully! Attachment of alkanethiols to gold to make them hydrophobic is the most common synthetic approach in nanotechnology syntheses. It turns out that the thinking about this that most people had was WRONG! According to p. 96, what happens to some of the gold during the self-assembly with the alkanethiols? 54) (p. 98) What are fractals, and how are they similar to dendrites? DNA Origami (dnaorigami.pdf) Briefly outline Rothemund’s technique for creating DNA origami. (p. 1) What structures does Aldman hope the planar self-assembling tiles can mimic? (p. 2) How can the dolphin’s tail be bent? (p. 3) What technique did Terao employ to create the nano-sewing machine? (p.4) Why is graphene the strongest material ever examined? (p. 4-5) Odd Shapes and Nanomachines (oddshapesandnanomachines.pdf) p. 1 (mid rt.) What could a molecular shuttlecock be used for? p. 2 (figure) Briefly explain how Stoddart's switch works. p. 4 topmid Can the macroscopic color of a material be controlled by the rotation rate of a molecular motor? p. 5 Explain how the molecular motor works. p. 7 How does the molecular rotor stick to a surface? What is/are the rotating part(s)? p. 8 bot. rt. Why does the molecule act like a molecular gyroscope instead of just a molecular rotor? p. 9 middle How does a molecular elevator work? p. 10 What enables molten metal to be transported along a nanotube? pp. 11, 12 How does one solder in a nanoworld? p. 13 right Why does a nanoring form in this case and not in others? p. 14 right How does one make nanotrees? p. 15 What is a double inclusion complex? p. 16 bot. right What is the significance of ship-in-a-bottle syntheses with nanotubes? p. 17 bot. left Explain how the DNA-based hand works. How was its performance verified? p. 18 How does a molecular abacus work? p. 19 How does one synthesize a molecular umbrella?

p. 20 How does one make "tweezers" using DNA? p. 21 Why does modification of an enzyme that helps synthesize ATP seem like a good choice for a molecular rotor? p. 22 right How does one complete the trefoil knot? p. 23 figure Look at the single molecule nano-car. p. 24 underlined Describe the process by which the artificial muscle works. p. 25 underlined What can a temperature-sensitive artificial muscle be used for? p. 26 arrow How does the artificial muscle expand or contract? p. 26 bracket Read the section on a robotic fuel cell. p. 31 underline What can the artificial muscle on p. 31 do? p. 33 bracket What two major themes in DNA nanotechnology does this project combine? p. 34 underlined Why is there so much reason for optimism for this technology? p. 36 underlined Describe how the motor in the nano-car on p. 23 works. p. 39 underlined How can molecular motors induce order in a moving system?

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
