Natural Polymers in Tissue Engineering

Abstract: The application of freeze dried hydroxypropyl methylcellulose (HPMC) and methylcellulose (MC) as stabilizers in peanut butter were investigated. These cellulose derivatives were dispersed in water and subsequently freeze dried and chopped to produce a stabilizer that is able to absorb high amounts of oil. Without this templating approach, HPMC and MC had no effect on peanut butter stability and texture. An alternative spray drying approach was attempted. There are numerous techniques for microfabrication of patterned polymer surfaces and microchips for drug delivery. While silicon has been the choice material for much of the research done with MEMS, the methacrylates and acrylates provide a rapid and inexpensive base for future work. new method for determining Rigidity temperature applying cooling curve analysis. The determined values of Rigidity temperatures for three AlSi8Cu3 alloys with different contents of Strontium using thermal analysis technique have been compared with Rigidity temperatures obtained using mechanical technique (viscosity measurement).
