Microencapsulation provides a simple and effective way to enclose bioactive material like drugs and cells, within a semi-permeable polymeric membrane, which could help the materials inside keep bioactive and release the polymeric substances or their products in a controlled fashion. The morphology of the microbeads was examined. The efficiency of these polymer microcapsules as containers for controlled...
The microbes are intimately to our lives, therefore the researches of behaviors of microbes such as growth, division, anastomosis, transfection, transformation, death etc. are very important. Traditional methods such as freeze-etching method, can only find different growing periods through different cells so there is still no definite evidence for the existence of some biological activities. This...
Research on encapsulation has much future potential in pharmacology and biochemistry. In this paper, we present an approach to manipulate the movement of sodium alginate beads in micro-channel. Electric field is an effective method to control the movement of droplets, but its current, if there is any, may cause extra heat and the fabrication of on chip electrode is also expensive. However, by mixing...
