Bio-Implants Derived from Biocompatible and Biodegradable Biopolymeric Materials
Published in P. Mereena Luke, K. R. Dhanya, Didier Rouxel, Nandakumar Kalarikkal, Sabu Thomas, Advanced Studies in Experimental and Clinical Medicine, 2021
For any polymer-based medical devices, an in-depth understanding of physical, chemical, biological, and engineering properties is highly relevant to get the performance. Efficient polymer-based medical devices and implants require the development of advanced instrumentation and characterization techniques, along with mathematical models to study the structure-property and functional performance relationships of various polymeric systems. Henderson et al. [19] give some of the concepts of NIST measurement technique can be used for tissue engineering which consists of high-throughput, combinatorial methods to produce test specimens of different material properties and advanced instrumentation procedures used for collecting data with high-resolution, noninvasive, multi-level imaging of cells and 3D visualization. Hassan et al. [20, 21] demonstrated the application of broadband dielectric spectroscopy can be used for the study of degradation polymeric materials.

Liquid crystalline phases can be identified by several techniques, such as polarizing light microscopy, differential scanning calorimetry (DSC), small-angle X-ray scattering (SAXs), low- frequency dielectric spectroscopy, nuclear magnetic resonance (NRM), Raman scattering spectroscopy, cryo-transmission electron microscopy (Cryo-TEM), or cryo-field emission scanning electron microscopy (Cryo-FESEM) [4,9].

Exposure to ionizing radiation has been proven to cause variety of cellular effects [1]. Of the most deleterious cellular effects of ionizing radiation comes the cell membrane damage. The fluidity of the cell membrane bilayer plays an important role in its functionality. Thus, damage in the cell membrane affects its functionality and the whole cell integrity [2]. Investigation of the cellular membrane damage is crucial when studying the cellular effects of ionizing radiation. The delectability of the radiation-induced damages relies essentially on the degree of the damage and the sensitivity of the detection techniques. Various physical techniques have been proven to be powerful, sensitive, and non-destructive techniques to investigate the radiation-induced damages at the cellular and molecular levels. Two of these techniques were used in this study, Dielectric spectroscopy and FTIR Spectroscopy.
