The Development of Centella asiatica Extract-Loaded BSA Nanoparticles Production to Improve Bioavailability (Assumption University)
Centella asiatica cBao-bog) is used as a traditional drug widely in Asia. C. asiatica crude extracts showed excellent potential in-vitro but less or no in-vivo activity due to their poor lipid solubility or improper molecular size or both, resulting in poor absorption, poor dosing and poor bioavailability. The Bovine serum albumin cBSA) can attract macromolecular and carry wide variety of molecule. So this research was aimed to develop C. asiatica extract-loaded BSA nanoparticles cCBNP) to improve bioavailability. CBNP was prepared ...
Effect of encapsulation on Zymomonas mobilis survival rate from practical conditions and its levan polysaccharide production ability (Assumption University, 2017-09)
Bioethanol is one of the good sources of liquid energy for automobiles and industries. The bioethanol market has continued to grow rapidly in recent years. Thai government aims to increase ethanol consumption from 1.2 billion liters in 2015 to 3.3 billion liters by 2021 and up to 4.1 billion liters by 2036. Z. mobilis, a gram-negative bacterium, is considered as an alternative organism in large-scale fuel ethanol production. The bacterium Z. mobilis is a highly potent ethanol producer already used in industrial-scale ...
Formation and stability study of flavor oil emulsions stabilized by polyglycerol esters and by sucrose esters (Assumption University, 2016-05)
In this work, flavor oil emulsions contained 5 wt% oil and 0.75 wt% emulsifier were formulated by using different combinations between flavor oils and food emulsifiers. Orange oil (00), peppermint oil (PO), polyglycerol monostearate (PGE), and sucrose monostearate (SE) were employed to form emulsions by ultrasonic homogenization. Heat stability (storage at 100°C for 30 min) and freeze-thaw stability (storage at -20°C for 22 h. and at 30°C for 2 h.) of emulsions were investigated by observing droplets under a microscope, ...

Surface Modification of Magnetic Iron Oxide Nanoparticles with Biodegradable Polymers for Plasma Protein Adsorption (Assumption University, 2017-09)
Magnetic iron oxide nanoparticles have been proposed as one of the most popular and efficient drug carrying magnetic materials used in human treatment and diagnosis due to their non-toxicity, high stability and high magnetic responses. Magnetic iron oxide nanoparticles (MNP) were obtained by chemical co-precipitation of iron salts in the presence of ammonia. The prepared magnetic particles were modified with gallic acid to reduce aggregation of particles, maintain magnetic stability, and slowdown degrading ...
