## Abstract Interaction of polyβΞ±,Lβglutamic acid (PGLA) with acridine orange (AO) was studied with circular dichroism and absorption spectra measurements. The following results were observed: (1) the addition of a comparable amount of AO with the glutamyl residue to the PLGA solution at pH of 4.5
## Abstract Circular dichroism and absorption spectra have been measured on solutions of acridine orange and poly(Lβglutamic acid) mixed at two molar ratios of carboxyl groupβtoβdye, P/D 25 and 0.8, and at different pH's. Characteristic circular dichroism is induced at the absorption bands of acrid
