Figure 4From: Controllable and switchable drug delivery of ibuprofen from temperature responsive composite nanofibers Ibuprofen release profiles from a) pNIPAM NFs containing 50 mg Ibuprofen/g NFs; b) PCL NFs containing 50 mg Ibuprofen/g NFs; c) pNIPAM and PCL composite NFs containing 50 mg Ibuprofen/g pNIPAM NFs. (*standard deviation bars were obtained from the measurements of triple diffusion studies. The level of significance was set at a p value of less than 0.05).Back to article page
