Researchers at Tufts University and Harvard University’s Wyss Institute have created tiny biological robots from human cells. The robots are called Anthrobots and are made from adult human tracheal cells.
The Anthrobots can move around in a lab dish and may one day be able to help heal wounds or damaged tissue. They can also encourage the growth of neurons across a region of damage in a lab dish.
The Anthrobots range in size from the width of a human hair to the point of a sharpened pencil. They can be spherical and fully covered in cilia, irregular or football shaped with more patchy coverage of cilia, or covered with cilia just on one side. They can travel in straight lines, move in tight circles, combine those movements, or just sit around and wiggle.
The impact on humans has not been thoroughly assessed yet. However, the advantages foreseen by using these tiny, often biological, machines mean it may well be only a matter of time till we see them become a solution in healthcare.
The multicellular biobots can move around and help heal “wounds” created in plated neurons. (MEDFORD, Mass.) – Researchers have created tiny biological robots, called Anthrobots, from adult human tracheal cells that can move across a surface and encourage the growth of neurons in a lab dish
Anthrobots are tiny robots made from human tracheal cells. They are able to self-assemble into different shapes and sizes. Each anthrobot is made up of a few hundred cells.
Anthrobots can:
- Move: They can move around and encourage the growth of neurons in a lab dish.
- Heal: They can heal damaged neural tissue.
- Self-assemble: They can self-assemble in lab dish environments.
Anthrobots are sourced from adults instead of embryonic cells. They started as a single, donated tracheal cell covered in armlike cilia. The cilia help the tracheal cells push out tiny particles that find their way into air passages of the lung.
Researchers chose this type of cell because they’re relatively easy to access due to work on Covid-19 and lung disease. In the future, Anthrobots might be used in personalized medicine.
Each Anthrobot starts out as a single cell, derived from an adult donor. The cells come from the surface of the trachea and are covered with hairlike projections called cilia that wave back and forth. The cilia help the tracheal cells push out tiny particles that find their way into air passages of the lung
Biological robots are synthetic lifeforms that are designed to perform a desired function. They are made by combining different biological tissues.
Biorobotics is the science of combining biology with mechanical systems to create machines that imitate biological systems. It combines the fields of biomedical engineering, cybernetics, and robotics.
Some examples of biological robots include:
- Xenobots These are the world’s first living robots. They are made from stem cells of the African clawed frog. They are less than a millimeter wide and can travel inside human bodies. Xenobots can self-replicate.
- Biomimetic robots These robots are inspired by nature and biology. They are fabricated using shape deposition manufacturing (SDM).
Multicellular biobots, also known as Anthrobots, are tiny biological robots created from human cells. They can move across surfaces and encourage the growth of damaged neurons in a lab setting.
Researchers at Tufts University and Harvard University’s Wyss Institute created Anthrobots from adult human tracheal cells. The biobots are spheroid-shaped and range in size from 30 to 500 microns. They have cilia facing outwards to propel the cells around.
Anthrobots exhibit diverse behaviors, including:
- Speed: 5 to 50 microns per second
- Motility patterns: Tight loops to straight lines
Researchers believe that Anthrobots could be deployed across a wide range of scenarios. (Full article source google)
