“…Similar absorptions were observed in the spectra of PMMAibuprofen, PMMA-tetracycline and PMMA-amoxicillin coatings. The FTIR spectra of ibuprofen [68] showed vibrational peaks at 935 cm −1 , which resulted from the O-H bending group of ibuprofen. Carbonyl stretching vibration (C=O) is observed at 1718 cm −1 , which corresponds to the carboxyl group (COOH) of ibuprofen.…”

Polymethylmethacrylate (PMMA) is a material of choice for many biomedical coating applications. However, such applications are limited due to the toxicity of the traditional solvents used for the solution processing of PMMA coatings and composites. This problem is addressed using an isopropanol-water co-solvent, which allows for the dissolution of high molecular mass PMMA and the fabrication of coatings by a dip-coating method from concentrated PMMA solutions. The use of the co-solvent offers a versatile strategy for PMMA solubilization and coating deposition, despite the insolubility of PMMA in water and isopropanol. Composite coatings are obtained, containing hydroxyapatite, silver oxide, zinc oxide, micron size silica and nanosilica. Such coatings are promising for the manufacturing of implants with enhanced biocompatibility, bioactivity and antimicrobial properties and the fabrication of biosensors. Ibuprofen, tetracycline and amoxicillin are used as model drugs for the fabrication of PMMA-drug composite coatings for drug delivery. The microstructure and composition of the coatings are analyzed. The versatile dip-coating method of this investigation provides a platform for various biomedical applications.

To solve the problems of limited drug solubility and poor biodistribution with polymers in drug delivery system, ibuprofen (IBU) is chosen to prepare IBU‐loaded poly(lactic acid) (PLA) micro‐fibrous mats via electrospinning. Distinguished from the previous studies, a lower toxic binary solvent dichloromethane/ethanol (DCM/EtOH, v/v = 8/2) is used to successfully fabricate PLA/IBU electrospun mats with outstanding properties. In order to further evaluate the effects of IBU content on PLA, there are characterization methods employed as follows: scanning electron microscopy (SEM), Fourier‐transform infrared (FTIR) spectroscopy, X‐ray diffraction (XRD), differential scanning calorimetry (DSC), and UV–vis spectrophotometer. The results show that IBU can be physically and uniformly distributed both on the surface and inside of PLA fibers. Compared with pure PLA mats, the crystallinity and mechanical properties of PLA/IBU electrospun mats has significantly improved. Meanwhile, in vitro drug release behavior demonstrates that with the increasing content of IBU, the rate of IBU release has increasingly improved. Particularly, the release behavior of PLA/IBU mats exhibited best with 20% IBU content, and the release amount reached 74.3% at the end of 240 h. Considering all these features, PLA/IBU electrospun mats have the potential to be used in the fields of wound dressing and drug delivery.
