Description
Summary:Bioresorbable polymeric materials are emerging biomaterials to meet the demands in the biomedical field such as tissue engineering, drug delivery and wound healing applications. The synthesized polymers were characterized by fourier transform infrared spectroscopy (FTIR),1H nuclear magnetic resonance (1H NMR) and13C nuclear magnetic resonance (13C NMR). The new emerging biomaterials are typically bioresorbable materials that are useful in diverse applications such as tissue engineering [1] drug delivery [2] and wound healing [3]. Wound care products, such as sutures, patches, and so on, are prepared using such resorbable polymers designed to eliminate the need for secondary medical procedures following the completion of the healing process. [...]there is a need to develop techniques to independently tune mechanical properties, degradation rates [5] and release properties of resorbable biomaterials. The synthesized polyesters were characterized by fourier transform infrared (FTIR),1H nuclear magnetic resonance (1H NMR) and13C nuclear magnetic resonance (13C NMR) spectroscope methods. CHARACTERISATION: 2.3.1 Solubility: Solubility of all the random polyesters was determined in various solvents qualitatively. 2.3.2 Fourier- Transform Infrared (FTIR) Spectroscopy: IR spectra of the polyesters were recorded by Perkin-Elmer IR spectrometer in the range of 4500 to 400 cm-1. The samples are embedded in KBr pellets. 2.3.31H nuclear magnetic resonance (1H NMR): 1H NMR spectra were recorded AV 3500 MHz Spectrometer by using DMSO as a solvent and the chemical shift values are reported in parts permillion (ppm). 2.3.413C nuclear magnetic resonance (13C NMR): The13C NMR spectra of the synthesised polyester were recorded at 300-600 MHz in deuterated chloroform as solvent...
