Shape-engineered nanostructure

Fig. 2.3 Schematic diagram of nanophotonic matching system. The function is based on a quadrupole-dipole transform via optical near-fleld interactions, tind it is achieved through shape-engineered nanostructures and their associated optical near-field interactions...

To verify this quadrupole-dipole transform mechanism brought about by shape-engineered nanostructures, we numerically calculated the surface charge distributions induced in the nanostructures and their associated far-field radiation based on a finite-difference time-domain (FDTD) electromagnetic simulator (Poyntingfor Optics, a product of Fujitsu, Japan). Figure 2.4a schematically represents the design... 

In this chapter, we focus on recent efforts to design and fabricate soft shape-memory materials, including both polymeric and supramolecular systems. We first classify these materials based on their micro- and nanostructure (Section 5.2.2). We then highlight how soft shape-memory materials have been applied to biomedical applications as implantables (Section 5.2.3.1), drug delivery devices (Section 5.2.3.2), and tissue engineering scaffolds (Section 5.2.3.3). In addition, we briefly discuss future trends for utilizing soft shape-memory materials for biomedical applications (Section 5.2.4).
