What is the main advantage of using hydrogels in drug delivery?
Hydrogels can absorb and release drugs in a controlled manner
What type of imaging uses a radiotracer to evaluate metabolic activity in tissues?
Positron Emission Tomography (PET)
Name one advantage of using synthetic scaffolds over natural ones.
Synthetic scaffolds can be designed with specific properties and are more consistent in structure
What type of prosthetic allows for movement through electrical signals generated by the user’s muscles?
Myoelectric prosthesis
Describe the purpose of a ventricular assist device (VAD).
It helps pump blood from the lower chambers of the heart to the rest of the body, often used in patients with weakened or diseased hearts.
Explain how surface modification can improve the biocompatibility of a biomaterial.
Surface modification can reduce immune responses, enhance tissue integration, or minimize bacterial adhesion by altering the material's physical and chemical properties
Explain why CT scans provide more detailed images of bones than X-rays.
CT scans take multiple cross-sectional images, providing a detailed 3D view, while X-rays are 2D projections
Describe the challenge of vascularization in tissue engineering.
Ensuring that engineered tissues have an adequate blood supply to deliver oxygen and nutrients to cells
Describe one ethical concern surrounding biomedical engineering innovations.
