    Figure 1: Schematic plot of enhanced chiral sensing. Although a much smaller amount of analytes was used in this experiment compared to the one in Fig. The first mechanism is based on the near-field enhancement factordefined as the near-field intensity in the vicinity of the metamaterial surface normalized to the far-field intensity.

    Eriksson, T. Chirality detection of enantiomers using twisted optical metamaterials. Increased sensitivity can also be achieved by incorporating a nanofluidic system and flowing chiral molecules between the twisted layers instead of atop.

    Our approach is ideal for sequential measurements using microfluidic systems of very small quantities of molecules.

    The main mechanism in this work relies on measuring the spectral shift in the far field spectrum due to the nearfield interactions between the chiral molecules and the metasurface. This treatment also left the metamaterial hydrophilic for better adhesion especially for the protein sample, which was prepared by spin-coating.

    This spectral extension is advantageous because long exposure to ultraviolet radiation can severely affect biomolecular samples.

    Three to five measurements were repeated on each sample across the metamaterial from top to bottom and the results were found to be consistent.

    The calibration, performed beforehand on the bare metamaterial samples, removes most of the errors stemming from fabrication differences between the two mirror-symmetric metamaterials.

    However, chiral molecules on their own typically possess extremely small CD, in the range of only few tens of millidegrees observable in the ultraviolet range 6. Cite this article Zhao, Y.

    CD spectra are calculated by extracting the ratio between the left-handed and right-handed radiated fields in the far field. The error bars indicate the standard deviation from the three repeated measurements of each analyte from bc. Our results are consistent with chirality assignment based on conventional CD measurements.

    2. First, the proposed method shows an inherent robustness to molecules with different molecular weight, solution quantity, buffer solution, and it is only sensitive to the handedness of the chiral molecules.
