Z-Scan technique: To measure the total protein and albumin in blood

Z-scan technique is an effective tool for measuring the optical nonlinearity of the materials. By using this technique the measurement was made for total protein and albumin. The nonlinear refractive index of the total protein and albumin were found to vary linearly with concentration. Hence by calculating the nonlinear refractive index it is possible to measure their concentration in the sample. The values measured thus are found in equivalence with conventional colorimetric method. Keywords: Z-scan Technique; Nonlinear Refractive Index; Total Protein; Albumin.
