Abstract

Find a way to distinguish the concentration of L-Phenylalanine in solution or blood is one of interesting topic in medicine. The effect of L-phenylalanine concentration on Rose Bengal in water and nonconfined droplet is studied by spectrophotometer, spectrofluorimeter and Z-scan instrument. The value of nonlinear absorption coefficient () and nonlinear refractive index (n2) of Rose Bengal in solution of L-phenylalanine with water and nano-droplet is studied by Z-scan instrument. The results indicated that the value of  change from 1.4 to 5.6×10−7 cm/W with increase of L-phenylalanine concentration at the aqueous solutions of Rose Bengal with concentration of 0.081 mM. While, the value of  is changing from 1.04 to 6.47×10−7 cm/W with increase of L-phenylalanine concentration 4.05×10−8 to 4.05×10−6 mM. The results indicated that the  values of Rose Bengal in nano-droplet are sensitive than aqueous solutions with change of L-phenylalanine concentration. The study of solution with spetrofolurometer indicated that the L-Phenylalanine don’t affect directly on fluorescence spectra of Rose Bengal in aqueous solutions and it can change in the solution of dye with nano-droplet.
