Mag-Instruments - Bacteriodrome and Magnetodrome
Magneto- and bacteriodrome are devices for microscopic observation of magnetic field influence on magnetic compounds or organisms. They originate from research on magnetotactic bacteria, but find their application in wide variety of fields, such as: medical research, biology or material science.
The device is primarily composed of four components:
- a digital microscope or zoom lens used for observation of a studied sample
- a source of magnetic field which allows for precise control of intensity and direction of the magnetic field to which the sample is subjected
- a non-magnetic motorized stage which allows for smooth control of the sample's location
- a control electronics and an advanced computer software which controls the entire system and allows for microscope image recording and vision processing
The system allows for flexible control of a magnetic field direction and intensity in the plane of the specimen. The field properties can be set as constant values or may vary over time. Examples of field control options:
- constant field in North, South, East or West
- circular rotation of the field
- constant switching between North-South or East-West
- manual control of the field direction and intensity through a joystick
- user defined field direction and intensity as function of time loaded from a *.csv file
The software provided with the instrument allows for control and monitoring of the state of the system. Additionally it allows capturing of the microscope camera image and provides a number of real-time vision processing functionalities, such as:
- tracking of moving objects and exporting their trajectories to *.csv file
- counting of moving objects
- thresholded view which simplifies visual identification of moving objects
- moving object trace recording and more
