We investigate QCD matter using the two-flavor PNJL model and find that the shear viscosity to entropy density ratio η/s reaches a minimum while the bulk viscosity ζ/s peaks near the chiral crossover line, particularly at large baryon chemical potential, indicating sensitivity to critical dynamics and offering potential signatures for the QCD critical endpoint in heavy-ion collisions.
