In this context, it is necessary to understand the color forming mechanism better in order to get target color and improve the yield. A detailed experimental study to investigate the relationship between the manganese content on color formation and the redox condition was carried out. All experiments were carried out at different level of iron and manganese oxides. Color parameters （dominant wavelength, brightness （%）, purity （%） and L-a-b values） were examined for large interval of batch redoxes. In this paper, the results of above mentioned experimental studies were discussed together.展开更多

The functionalisation is achieved by standard aminealdehyde （Schiff base） reaction through the crosslinker, glutaraldehyde. To prove the ability of the RCA 120 modified PMMA surface, the PC 12 cell line （rat pheochromocytoma ceils） has been captured and cultured by the microfluidic device. In the presence of tunicamycin, the dose/timedependence on decreasing of binding affinity of RCA 120 modified device with PC 12 cell is also observed. The experimental results demonstrate that the lectin-functionalized microfluidic device can be employed as efficient cell culturing platform, and has a great promise of being used as a powerful tool for monitoring the interaction of drug with living cell.展开更多
