Fourier-Transform Infrared Spectroscopy of Antibiotic Loaded Ag-Free and Ag-Doped Hydroxyapatites

Tailored therapeutic release from polycaprolactone-silica hybrids for the treatment of osteomyelitis: antibiotic rifampicin and osteogenic silicates

“…22 An alternative hypothesis is that the 958 cm −1 could be ascribed to minor Si-OH stretching while the shoulder peak to the vibrations of methyl and methylene groups in rifampicin. 60 These results substantiate the successful loading of rifampicin, as previously verified by spectrophotometry. The antibiotic seems well dispersed inside the material and interacting with both the organic (PCL) and inorganic (silica) components of the single-phase hybrid.…”

Enhanced adsorptive removal of rifampicin and tigecycline from single system using nano-ceria decorated biochar of mango seed kernel

“…The peak at 1725 cm −1 could be allocated to C O group. Also, the C C stretching might be assigned by a significant absorption band at 1562 cm −1 [ 64 , 77 ]. However, the spectrum of Ce–Py–MSK after RIFM adsorption shows the existence of the bulk of the RIFM peaks, indicating that the RIFM was successfully adsorbed onto the biochar surface.…”

Synthesis and Application of Cobalt Oxide (Co3O4)-Impregnated Olive Stones Biochar for the Removal of Rifampicin and Tigecycline: Multivariate Controlled Performance

“…The obtained data reveal the presence of characteristic peaks of free RIFM, including the two bands at 2934 and 2867 cm −1 which are associated with the C–H and =C–H stretching. Furthermore, the strong absorption band at 1555 cm −1 may be assigned to the C=C stretching [ 52 , 53 ]. Nevertheless, the FT-IR spectrum of RIFM@Co-OSBC shows the presence of the RIFM peaks with a slight shift such as the absorption band at 1555 cm −1 in the RIFM spectrum also appears at 1552 cm −1 after the adsorption process confirming the successful adsorption of the RIFM onto the Co-OSBC.…”
