The purpose of this study is to examine the effect of gamma radiation and UV radiation on the microstructure, chemical structure and thermal stability of Chitosan/Mimosa Tenuiflora and Chitosan/Mimosa Tenuiflora/MWCNT composites scaffolds produced by thermally induced phase separation. The composites were irradiated and observed to undergo radiation-induced degradation through chain scission. Morphology, thermal properties and effects on chemical and semi-crystalline structures were obtained by scanning electronic microscopy (SEM), thermogravimetric analysis (TGA), differential scanning calorimetry (DSC), FT-IR analysis and X-ray Diffraction. A relationship between radiation type and the thermal stability of the composites, were also established. This relationship allows a more accurate and precise control of the life span of Chitosan/Mimosa Tenuiflora and Chitosan/Mimosa Tenuiflora/MWCNT composites through the use of radiation in materials for use in tissue engineering.

“…The IR analysis of the scaffolds revealed the presence of bands at 563, 601, and 1034 cm −1 , which can be attributed to the bending vibration of the PO 4 3− groups. In the same way, inorganic carbonates (CO 3 2− ) are appreciated at 880, 1427, and 1506 cm −1 [23, 24]. This suggests that the formation of phosphate and carbonate crystals was favored.…”

“…4g) show small peaks reflections since the first week that correspond to the most intense peaks of hydroxyapatite phase (31.7 and 46.7°). After the second week, the hydroxyapatite phase is confirmed by the presence of a third peak at 75.3° [23, 27]. In addition, a peak at 57° and 66° are detected that could relate to the octacalcium phosphate and calcium carbonate crystalline phases [28, 29].…”

“…These phases are the same that the chitosan scaffolds detected phases. During the complete study, the diffractograms of the functionalized scaffolds by mixing exhibit hydroxyapatite peaks at 25.8°, 31.7°, 46.7° and 75.3° [23, 27]. Also, peaks are observed at 19.9° (assigned to dicalcium phosphate dehydrate), 66° (attributed to calcium carbonate), 57° (octacalcium phosphate) and 14° (chitosan) [28, 29].…”

Biomineralization is the process by which diverse organisms have the capacity to create heterogeneous accumulations, derived from organic and inorganic compounds that induce the process of mineral formation. An example of this can be seen an extrapallial protein (EP) of Mytilus californianus , which is responsible for carrying out the biomineralization process. In order to determine their ability to perform the biomineralization process, EP protein was absorbed and mixed in chitosan scaffolds which were tested in simulated physiological fluid. The materials were analyzed by FTIR spectroscopy, field emission scanning electron microscopy-energy-dispersive electron X-ray spectroscopy andX-ray diffraction. Results confirmed that the EP protein stimulates the rapid growth of biological apatite on the chitosan scaffolds. The mixing method favored more the apatite growth as well as the formation of second nucleation sites than the immersion method.

“…Although there has been significant work done on the conjugation of chemically synthesized magnetite NPs to antibodies [10][11][12][13][14][15] there have been relatively few studies comparing the influence of antibody immobilization method in effectiveness of antigen detection. The conjugation of the proteins with magnetic NPs can be done via physical adsorption using polymer coatings, such as dextran, and by covalent immobilization using amino derivatives, such as aminosilane [3].…”

Considerable effort has been focused on improving the control of size, shape, and surface modifications to detect proteins. The purpose of this study was to compare the efficiencies of aminosilane-coated magnetite (As-M) nanoparticles (NPs), dextran-coated magnetite nanoparticles (Dx-M), and bare nanoparticles for conjugating single-chain variable fragment antibodies (scFvs) with the aim of detecting the human epidermal growth factor receptor 2 (HER2) protein. Dx-M and As-M NPs were characterized using scanning electron microscopy, energy dispersive X-ray spectroscopy, X-ray diffraction, and Raman spectroscopy. Dx-M and As-M were conjugated with a monoclonal scFv for active targeting of the HER2 antigen. Aminosilane surface coating enhanced the scFv conjugation efficiency over twofold compared to that of the dextran-coated magnetite NPs for the detection of HER2 proteins.
