Table 1 Measured refractive index for achieved biosilica. Data are obtained by confocal imaging of light reflected from borosilicate/biosilica interfaces (see the text). The value of n at 633 nm is extrapolated by the fit of experimental data through a Cauchy model with coefficients (± s.d.) A = 1.46±0.01 and B = (3.5 ± 1.5) ×103 nm2
