3 (Atomic and Molecular Level Interaction/Property/Function, 20 pts) The material assemblies of atoms and molecules are important in biomaterials and can influence the properties of device. Below are some examples of devices with different properties. The orthopedic plastic is dense and lubricious, the catheter is soft and elastic, and the hip joint is strong and hard. Orthopedics plastic: dense and lubricious Catheter: soft and elastic Hip joint: hard and strong a. Comment on the differences in property-function relationship for the devices b. Comment on how their atomic and molecular arrangement may differ to result in such difference in properties C. Comment on how their inter-atomic and inter-molecular forces may differ to result in such difference in properties d. What material modification can change a soft silicone catheter to become dense? e. What material modification can make the surfaces of catheters lubricious or have low friction
