100% organic micro-body thrust

The development of (micro) systems capable of being moved and propelled by simple external stimuli such as light is a burgeoning field with many potential applications ranging from nanomedicine to water pollution control. To move, most current modular or hybrid systems require a irritable (Fuel is a substance that, in the presence of oxygen and energy, can …) Synthetic or semi-natural.

Chemists from Bordeaux recently developed a completely different type strategy (Strategy – from the Greek word stratos which means “army” and Ageîn which means…) who uses theOxygen (Oxygen is a chemical element of the family of chalcogens, from…) Issued by papers through Photosynthesis (Photosynthesis (Greek φῶς phōs, light and …) to push them in a controlled manner space (Surface generally refers to the surface layer of an object.

Over millions of years of evolution and improvement, nature has designed highly sophisticated dynamic systems of varying sizes. Natural swimmers are a beautiful (Named in honor of inventor Alexander Graham Bell, Bell is a unit…) for example complication (Complexity is a concept used in philosophy and epistemology (for …) for evolution, which uses highly diverse strategies to generate traffic.

These swimmers can be operated and controlled externally, for example by light, but also by a Energy (The word force can refer to a mechanical force on things, and also, figuratively, a…) magnetic, electric or My voice (Sound science is a branch of physics that aims to study…). It can also be propelled by other mechanisms, based on the use of chemical (bio)fuels, but with the particular risk that fuel (Fuel is the fuel that powers a heat engine. This turns…) Or the reaction products are toxic. Recently, hybrid micro-swimmers have been proposed as an interesting mediator between natural and synthetic swimmers. They are often made up of purely synthetic parts combined with biological entities such as bacteria (Bacteria (Bacteria) are prokaryotic unicellular organisms, characterized by …) or sperm.

Upon contact with water, a leaf modified in this way becomes a natural or microbial swimmer.

Unlike the majority of systems reported to date, there is no conventional chemical fuel, such as peroxide (Peroxide is a chemical compound with the general formula ROO-R’, group -OO -…) Fromhydrogen (Hydrogen is a chemical element with symbol H and atomic number 1.) or other vehicles such as Sugar (What is commonly called sugar is, since 1406, “a substance with a sweet flavour…) For some enzyme swimmers, it is only necessary to activate the leaf. This moves only under the influence of light, in the presence of carbon dioxide. carbon (Carbon is a chemical element of the family of crystalline substances, symbol C, …) And water. This unique class of natural swimmers in the future can serve as a platform for the development of original dynamic systems at different levels.
