Micro-nano robots intended for application to various fields are developed. However, motors, which are robot's power, are not yet practical. In this paper, to realize the motor, which can be applied to micro-nano robot's power source, we established bio-motor by using surface swarming of Vibrio alginolyticus. We succeeded in controlling movement of surface swarming by ratchet shape micro channel and...
Recently, micro-nano robots intended for application to various fields are developed. However, motors which are robot's power are not yet practical. In this paper, to realize the motor which can be applied to micro-nano robot's power source, we established bio-motor by using surface swarming of Vibrio alginolyticus. First, we succeeded in driving the micro gear in the closed micro channel. Next, to...
Toward to realizing establishment of new micro robot for micro-nano surgery, drag delivery etc., many people proposed microbe as actuator. So, evaluation of microbe property for these application arias is important. From this viewpoint, we try to fabricate evaluation tool for bacterial behavior in micro channel like capillary vessel. This evaluation will be helpful to our recent study “bacteria driven...
In this paper, we established the driving systems for micro structures by using surface swarming of Vibrio alginolyticus. First, we succeeded in causing rotational movement using ratchet shape micro channel. Next, To rectify rotational movement, we fabricated center prior in the micro channel. We succeeded in smooth rotational movement using this new design micro channel. Furthermore, we succeeded...
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...

In this paper, we established the transport systems for micro object by using surface swarming of Vibrio alginolyticus. First, we confirmed that V. alginolyticus were able to transport the micro beads. In this experiment, we used YM19 and YM19ΔcheY that were a kind of the variant strain of V. alginolyticus appropriate for surface swarming. Next, we examined relationship between the transport speed...
This paper presents a nanoprobe insertion for nanoinjection applications for biological species based on environmental-scanning electron microscope (E-SEM) nanorobotic manipulation system. Based on the bio-nano manipulation system, we have been proposed a nano-injection method by nanoprobe insertion. The nanoprobe is designed to have a sharp tip to insert the probe into biological specimen. It is...
In this paper, we established the transport systems for micro structures by using surface swarming of Vibrio alginolyticus. First, we confirmed that YM19 and YM19ΔcheY, that were a kind of the variant strain of V. alginolyticus appropriating for surface swarming, were able to transport the micro beads. Next, we examined relationship between the transport speed and the diameter of the micro bead. The...
We propose in situ formation of gel microbeads made of a thermoreversible hydrogel for indirect laser micromanipulation of microorganisms, DNA and viruses. Irradiation, using a 1064 nm laser, of an aqueous solution mixed with poly-(N-isopropylacrylamide) through a high magnification lens resulted in the formation of a gel microbead at the laser focus due to heating. The gel microbead was trapped by...
Isolation and separation of the target microbial cells is quite important in applied microbiology. We propose a new touch sensor for separation of the target cells on the plate using a micromanipulator with a glass pipette. Principle of this touch sensor is based on detection of mechanical impedance change after contact of the vibrating pipette tip with the plate. We fixed the sensor on the pipette...
