Engineering Magnetotactic Bacteria as Medical Microrobots

Advanced Materials, EarlyView.
Magnetotactic bacteria (MTB) are living microorganisms that produce magnetosomes for navigation using the Earth's geomagnetic field. Their built‐in magnetic components, along with their intrinsic and/or modified biological functions, make them one of the most promising platforms for making future living and programmable microrobots.

Study of the isolated bacteriophage ΦAb-Sр7 adsorption on the cell surface of the Azospirillum brasilense Sp7

Вопросы вирусологии, 2016
The bacteriophage ΦAb-Sр7 was isolated from the cells of the azospirillum brasilense sp7. The morphology, size of the gram-negative colonies, and range of lytic activity against other strains and species of the genus Azospirillum was tested. The isolated

Micro‐ and Nano‐Bots for Infection Control

Advanced Materials, EarlyView.
This review presents a strategic vision for integrating micro‐ and nanobots in the pipeline for infection diagnosis, prevention, and treatment. To develop these robots as a practical solution for infection management, their design principles are clarified based on their propulsion mechanisms and then categorized infection management domains based on ...

Chemotaxis of ciliated microorganisms: with and without noise [PDF]

arXiv, 2018
Biological systems like ciliated microorganisms are capable to respond to the external chemical gradients, a process known as chemotaxis which has been studied here using the chiral squirmer model. This theoretical model considers the microorganism as a spherical body with an active surface slip velocity.

Vision Transformers for Weakly-Supervised Microorganism Enumeration [PDF]

arXiv
Microorganism enumeration is an essential task in many applications, such as assessing contamination levels or ensuring health standards when evaluating surface cleanliness. However, it's traditionally performed by human-supervised methods that often require manual counting, making it tedious and time-consuming.
