This study demonstrates the feasibility of using rock salt as a modifier to alter the optical reflectance and morphology of poly(vinyl alcohol) cryogel for optical tissue phantoms. The methodology used simplifies the preparation process and shortens the synthesis time. In certain limit, this simple method of rock-salt modification is effective in controlling the optical reflectance and obtaining a smoother structure of poly(vinyl alcohol) cryogel. Profile analysis showed the sensitivity of several wavelength points of poly(vinyl alcohol) cryogel reflectance spectra but with different responses to the various rock-salt concentrations. Poly(vinyl alcohol) cryogel generated by simple rocksalt modification may be useful for mimicry of certain tissues in optical tissue studies.
