Megjegyzések:	The sensitivity and optical properties of silver nanoprisms (triangular plateswith round-truncated corners) are investigated in this paper. Results ofboundary element method simulations are compared with experimentalresults and literature data. Based on electron microscopy images of thesynthesized nanoprisms, a single-particle model is set up for simulations withthree running parameters: edge length, thickness, and roundness (defined asthe radius of the circumscribed circle divided by the edge length). Thesegeometric parameters can be optimized during chemical synthesis to createsensors with improved sensitivity. The effect of biomolecular layers is alsoinvestigated. As a novel approach to improve the agreement between thesimulated and experimentally measured extinction spectra, the single-particlemodel is extended to consider the variation of the prisms' parameters in theform of distributions. The resulting extinction cross-section spectracorrespond well with the experimental data. The calculated bulk refractiveindex sensitivity is 670 nm/RIU (RIU stands for refractive index unit) for thesingle particle model (length=150 nm, thickness=10 nm, and roundness=0.1), while (690?5) nm/RIU for the extended model. The presented modeland obtained relations between sensitivity and geometry can be effectivelyused to design and optimize the fabrication technologies for silvernanoprism-based sensing applications.
