Helical structure assembled by hydrogel microfibers is significant for culture of smooth muscle cells. However, the helical structure is only fabricated at the macroscale, while the fabrication of helical microstructure is still a challenge due to the lack of assembly method. In this paper, we propose a robotics-based assembly method to handle such challenge. An electromagnetic needle (EMN) is employed...
In this paper, we propose a method of cell assembly on microstructures of a biodegradable material for the regeneration of living tissue. The adhesion of fabricated biodegradable structures on the substrate was one of the important challenges. The material was tested trypsin EDTA-dipped Dialysis membrane. The results show that one side of the microstructure after 2 minutes was peeled off, but I did...
In this paper, we develop the Catalytic Nano-mobile Robot (CNMR) with finely designed geometry swimming in hydrogen peroxide solution as a novel type of nano machine. First we use Focus Ion Beam (FIB) etching to fabricate the nano- mobile robot into the geometry or shape as we desire freely with little constrain. And then an effective and stable manipulation method in sub micrometer scale and liquid...
Micro/nano robots have been actively studied to lead the developments of the novel technologies, such as drug delivery systems (DDS) and micro/nano surgery inside human body. Recently, the micro living organisms, especially flagellated bacteria, have been used as the driving forces for the microobjects. To achieve the more precise control of the bacteria-driven microobjects, we previously developed...
Micro/Nano robots have attracted scientific attention to develop novel technologies such as drug delivery systems. Recently, flagellated bacteria have been used as the driving force of microobjects to develop bacteria-driven microrobots. In this paper, we propose a method of smart manipulation of multiple bacteria-driven microobjects with single manipulated guiderobot based on bacterial autonomous...
