Hydroxyapatite-collagen composite is a prosperous biomaterial in reconstructive surgery for the reparation of defects within human hard tissue. Within this research, three-dimensional blocks of HAp/collagen composite biomaterial were synthesized by homogenizing the HAp/collagen mixture by cold and hot (T=60oC) pressing (P=49 MPa). The changes in the system were followed by using thermal analysis (DSC & TGA), FT-IR spectroscopy and scanning electron microscopy (SEM). The identification and kinetic analysis of appearing phase transition were done. FT-IR spectrum of the biocomposite shows that neither cold nor hot pressing had significant influence on the individual components of the composite. SEM of the fracture …

Polymerase chain reaction (PCR) is a technique that can amplify a specific DNA segment in vitro using two site specific primers that hybridise to opposite DNA strands. The method produces large amounts of specific DNA from a complex DNA template in a single enzymatic reaction within a matter of hours. Reaction mixture contains a double helix DNA, two target specific primers, dNTPs, a DNA polymerase and a Mg2+ containing buffer. PCR is carried out in three distinct steps i.e. denaturation step, annealing step and extension step, which are repeated many times. The efficiency of PCR is measured in terms of …
