TEMPS is compatible for reversible apposition with the sinonasal epithelium. (A) Absorbance measurements at 415 nm as a function of increasing temperature for samples (n = 4) of thermogel and TEMPS showing that both undergo phase transition at 34–35 °C. (B) The reversible temperature-responsive phase change of TEMPS demonstrated by repeated absorbance measurements at ambient temperature and 37 °C over 28 days. (C) Cytocompatibility of the thermogel with RPMI 2650 cells showing that viability is maintained after 24-h incubation with gel. Cell viability was measured using PrestoBlue reduction and % viability was calculated relative to positive (+) and negative (−) controls.
