Structural information can be obtained using X-ray diffraction (for AH adjuvants only), spectroscopy (FTIR, NMR, Raman) and transmission electron microscopy. Granularity Aluminum adjuvants typically consist of primary nanoparticles that form irregularly shaped aggregates ranging in size from 1 to 20 μm. ...
By: Ali Ibrahim Shar, Gul Afshan Soomro, Ghulam Abbas Shar, Muhammad Bachal Korai Abstract Forty (40) specimens of the gallstones were taken from the infected peoples who were admitted and cured in the Peoples University of Medical & Health Sciences for Women, Shaheed Benazirabad, Nawabshah, Sindh, Pakistan. In our work gallstones (total 40) were found in the age ranges from 20-60 years for ...
In this study, we synthesised ZnS nanocrystals and embedded them in polyacrylamide (PAAm) hydrogel to stabilise the fluorescence emission for biomedical applications. ZnS nanoparticles have strong emission but they lose it in time, so generally they are capped with polymers. We capped ZnS nanoparticles with (3–mercaptopropyl)–trimethoxysilane (MPS) and then dispersed them through the PAAm ...
Phase identification, microstructural observations and elemental analysis of the as–synthesised BCP particles are conducted by using X–ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), environmental scanning electron microscopy (ESEM) and X–ray fluorescence (XRF).Keywords: tricalcium phosphate, hydroxyapatite, hydrolysis, biphasic calcium phosphate, ...
Also the sustained release effect over four weeks of FTIR–OVA microspheres was obtained by PEI modified PLA lamellae. In vitro release profiles show more active protein sustain release from PEI modified PLA lamellae than OVA–PLA only microspheres. ...
The scanning electron microscopy (SEM) data have shown the RSV nanoparticles in the collagen material, and Fourier transform infrared spectroscopy (FTIR) detected the adsorbed RSV nanoparticles at 950-1000 nm. In theory, collagen has similar properties to an emulsion/solvent that cause nanoformation of RSV under homogeneity of stirring. ...
Early results indicate that all sterilisation techniques affect collagen properties but suggest that the least damaging of the techniques investigated was γ irradiation.Keywords: sterilisation, collagen, Chondrosia reniformis, autoclave, gamma irradiation, ethylene oxide, denaturation, Fourier transform infrared spectroscopy, FTIR, differential scanning calorimetry, DSC, chain ...
Various compositions of p(MMA–co–TIPA) were physico–chemically and biologically characterised through FTIR–ATR, SEM, EDX, in vitro biocompatibility and X–ray measurements. ...
The chemical structure of the hydrogels was confirmed by means of attenuated total reflectance Fourier transform infrared spectroscopy (ATR-FTIR). In all cases, drug dissolution analysis showed that the active agent was released at a slower rate with hydrogels that contained acrylic acid.Keywords: drug dissolution, hydrogels, wound healing, polyvinyl alcohol, PVA, polyacrylic ...
