Mineral content of collagen sponges mineralized via the polymer-aided process. PILP-mineralized collagen samples treated with 50 µg/mL poly-L-aspartic acid, 50 µg/mL poly-L-glutamic acid, 1,000 µg/mL polyvinylphosphonic acid or a combination of polymers for 3 and 6 days. Total percent of mineral present in the samples was determined using thermogravimetric analysis. A heating rate of 5 °C/min was applied in the temperature range of 30–800 °C under air at a flow rate of 100 mL/min. To compare the degree of mineralization, the material remaining at 600 °C was interpreted as the mineral content since the organic portion of the samples should be totally combusted by 600 °C in an oxygen-containing environment.
