4. You are engineering new amphiphilic molecules that self- assemble into nanoparticles capable of delivering small molecule drugs in the body. a. You made your first new molecule, and you record the following measurements: Area of the head group is 35 Volume of the fatty tail is 640 Effective length of the tail (accounting for gyration) is 18.3 What type of assembly will form if a high concentration of this amphiphile (i.e., beyond the CMC) is mixed in water? b. You engineered a second molecule where V decreased to 250 ', but the other values remain the same. What is the new C and what type of assembly will form? PP c. If V was fixed at 640 ', how else might you engineer the amphiphile to achieve the same structure as in b? Describe the physical characteristics of the amphiphile you'd like to design and indicate the most auspicious parameter
