Precise detection of circular dichroism in a cluster of nano-helices by photoacoustic measurements
Abstract Compact samples of nano-helices built by means of a focused ion beam technology with large bandwidth and high dichroism for circular polarization are promising for the construction of built-in-chip sensors, where the ideal transducer must be sufficiently confined without compromising its fi...
