The convergence of materials and the life sciences is taking place on multiple fronts, with researchers in many different fields applying their expertise to improve diagnostics, therapy, implant materials, imaging, and drug delivery. Materials of all kinds, but especially nanomaterials, are being exploited for image enhancement, drug delivery, wound healing, electronic/photonic/fluidic devices for diagnosis and therapy, and regenerative medicine. At Penn State, there is a long history of accomplishments in ultrasound and the transducer materials that enable them. Similarly, metamaterials and other composites are being developed to enhance magnetic resonance imaging (MRI). Our expertise in nanoparticle and colloid chemistry is an ideal platform for new drug delivery strategies combined with image enhancement (targeting, tracking, treating), and at the same time, understanding and modifying the properties of viruses as therapeutic agents. For regenerative medicine, materials with bioactive hierarchical structures and/or functional nanostructured coatings can provide support to growing tissue, help nerves regenerate, or provide an interface for medical implants. Many of our researchers work directly with clinicians within Penn State's Hershey Medical Center and the College of Medicine, and with life scientists within the Huck Institutes. MRI faculty are exploring at the far reaches of next-generation medical materials and devices.
