In this experiment, we get to know Marimo. Through '''microscopic observation''', you can see that Marimos '''perform photosynthesis'''—they release tiny oxygen bubbles. Look closely—maybe you can spot them! | |||
At the '''smallest magnification''' under the microscope, you can observe individual structures of '''Aegagropila linnaei''': '''Algal filament cells''': Small, chain-like structures that form the dense network of the Marimo. '''Chloroplasts''': Tiny green organelles that capture light for photosynthesis—this is where oxygen is produced '''Oxygen bubbles''': Small, clear spheres attached to the algae filaments—visible proof of active photosynthesis. '''Bacteria or microorganisms''': Sometimes, you may see tiny life forms that live in '''symbiosis''' with the Marimo. | |||
Watch carefully—how do the bubbles change when you shine light on the Marimo?[[File:Marimo.jpg|thumb|659x659px]] | |||

Researchers explore Marimos as eco-friendly sensors that detect environmental changes and perform mechanical actions, making them a sustainable alternative to synthetic sensors. | Researchers explore Marimos as eco-friendly sensors that detect environmental changes and perform mechanical actions, making them a sustainable alternative to synthetic sensors. | ||

- Rising: When enough oxygen bubbles form, the Marimo ball becomes lighter and rises because the bubbles increase buoyancy. | - Rising: When enough oxygen bubbles form, the Marimo ball becomes lighter and rises because the bubbles increase buoyancy. | ||

In comparison, synthetic chemical sensors are based on artificial materials and technologies that detect specific chemicals or changes in the chemical environment. They consist of a sensing material that reacts with the target chemical, a transducer that converts this reaction into an electronic signal, and a processing unit that displays the results. There are various types of such sensors, including gas sensors, which detect gases like oxygen or methane; ion sensors, which measure specific ions in liquids; and optical sensors, which detect changes in light caused by chemical reactions. A subset of these sensors are biosensors, which combine synthetic components with biological elements. | In comparison, synthetic chemical sensors are based on artificial materials and technologies that detect specific chemicals or changes in the chemical environment.

Synthetic chemical sensors offer high sensitivity, fast and accurate measurements, and are often compact and easy to integrate. However, they are often expensive, have a limited lifespan, and sometimes use non-biodegradable materials. In contrast, living biosensors like Marimo balls utilize biological reactions as their mechanism and provide a more environmentally friendly and sustainable alternative for many applications. This research demonstrates how Marimo balls could offer an innovative way to monitor ecosystems while preserving the environment. | [[File:Th (9).jpg|thumb|401x401px]]Synthetic chemical sensors offer high sensitivity, fast and accurate measurements, and are often compact and easy to integrate.
