On the Measurement of the Effective Refractive Index of Biological Colloids
We address the problem of measuring the refractive index of biological materials. We limit our analysis to the case of colloids and consider the use of common automatic critical-angle refractometers to measure their effective refractive index. We provide rough guidelines to when these refractometers will incur in large errors and alternative techniques should be used.
