“…The existence of low-intensity bands at about 870 cm −1 may be ascribed to the ν 2 bending mode of CO 3 2− (C-O bond) in CHA and confirmed the presence of carbonated apatite in the samples [32]. No specific bands attributable to oxyhydroxyapatite Ca 10 (PO 4 ) 6 (OH) 2−2x O x were detected in our spectra; however, such bands were present for the CHA thin films deposited on Si substrate [35]. The most intensive Raman bands were observed for the CHA sample having 25 layers.…”

Characterization of Sol-Gel Derived Calcium Hydroxyapatite Coatings Fabricated on Patterned Rough Stainless Steel Surface

et al. 2019

Sol-gel derived calcium hydroxyapatite (Ca10(PO4)6(OH)2; CHA) thin films were deposited on stainless steel substrates with transverse and longitudinal patterned roughness employing a spin-coating technique. Each layer in the preparation of CHA multilayers was separately annealed at 850 °C in air. Fabricated CHA coatings were placed in simulated body fluid (SBF) for 2, 3, and 4 weeks and investigated after withdrawal. For the evaluation of obtained and treated with SBF coatings, diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS), X-ray diffraction (XRD) analysis, Raman spectroscopy, XPS spectroscopy, scanning electron microscopy (SEM) analysis, and contact angle measurements were used. The tribological properties of the CHA coatings were also investigated in this study.

“…The band at about 960 cm −1 is due to ν 1 (A 1 ) symmetric stretching vibration of the tetrahedral PO 4 3− group. This band was the most intense in the Raman spectrum of the CHA sample synthesized on a silicon nitride substrate [35]. For the specimens in this study, the intensity of this band was substantially less.…”

“…Furthermore, the disappearance of the hydroxyl bands at ~3570 [305][306][307] and ~630 cm -1 [306,307] that is associated with dehydration, is indicative of a phase transformation to an anhydrous calcium phosphate, possibly -TCP. Another previously encountered bands include at ~ 1120 [308][309][310][311] and ~ 945 cm -1 [307,309,312], which have also been ascribed to -TCP, and verified by XRD [308][309][310] and EDX [309]. Regarding TTCP and -TCP, a broad band between 1200 to 950 cm -1 has previously been attributed thereto [298,313].…”

“…Regarding the ACP component, one notices the presence in MAPLE film vs. composite powder of the following peaks: 1569 vs. 1564 (CO); 1457 vs. 1450 (CO3); 1417 vs. 1422 (CO3); and 1105 vs. 1075 (ν3PO4, shoulder) [61]. The low resolution of these peaks is characteristic of ACP [62].…”

Composite Drug Delivery System Based on Amorphous Calcium Phosphate–Chitosan: An Efficient Antimicrobial Platform for Extended Release of Tetracycline

et al. 2021

View full text Add to dashboard Cite

One major warning emerging during the first worldwide combat against healthcare-associated infections concerns the key role of the surface in the storage and transfer of the virus. Our study is based on the laser coating of surfaces with an inorganic/organic composite mixture of amorphous calcium phosphate–chitosan–tetracycline that is able to fight against infectious agents, but also capable of preserving its activity for a prolonged time, up to several days. The extended release in simulated fluids of the composite mixture containing the drug (tetracycline) was demonstrated by mass loss and UV–VIS investigations. The drug release profile from our composite coatings proceeds via two stages: an initial burst release (during the first hours), followed by a slower evolution active for the next 72 h, and probably more. Optimized coatings strongly inhibit the growth of tested bacteria (Enterococcus faecalis and Escherichia coli), while the drug incorporation has no impact on the in vitro composite’s cytotoxicity, the coatings proving an excellent biocompatibility sustaining the normal development of MG63 bone-like cells. One may, therefore, consider that the proposed coatings’ composition can open the prospective of a new generation of antimicrobial coatings for implants, but also for nosocomial and other large area contamination prevention.
