In the realm of scientific research, where innovation often collides with financial constraints, the story of chemist Biljana Mojsoska at Roskilde University in Denmark stands as a testament to the power of ingenuity and resourcefulness. As Mojsoska delved into the intricate world of nanosheets, an antibacterial coating with immense potential for medical applications, she faced a formidable challenge: an equipment failure that threatened to derail her research.
The Need for a Low-Cost Solution
The equipment in question was a sophisticated machine used to rotate sample vials containing the nanosheet coating. This rotation process was crucial for the coating’s effectiveness, as it ensured uniform distribution and optimal properties. However, the cost of replacing the failed machine was prohibitive, posing a significant obstacle to Mojsoska’s research.
The FabLab RUC’s Ingenious Response
Undeterred by the setback, Mojsoska turned to Jakub Klust and Bo Thorning, two creative minds from FabLab RUC, a makerspace known for its rapid prototyping capabilities. Together, they embarked on a mission to create a low-cost alternative to the expensive machine, utilizing the FabLab’s resources and expertise.
The Birth of the DIY Nanosheet Machine
Drawing inspiration from the principles of simplicity and affordability, Klust and Thorning set about designing and constructing a device that could replicate the functionality of the failed machine. They ingeniously employed a servo motor, controlled by an iRobota Uno microcontroller, to rotate the sample vials. A user-friendly interface, consisting of buttons, an encoder, and a small display, provided intuitive control over the rotation process.
Ensuring Reliability and Precision
Recognizing the importance of reliability in scientific research, Klust and Thorning meticulously incorporated gear reduction on the servo motor. This clever modification minimized vibration during the extended rotation periods required by Mojsoska’s research, ensuring the integrity of the nanosheet coating.
Open-Source Access to the Design
In the spirit of scientific collaboration and knowledge sharing, FabLab RUC has generously made the design details of their DIY nanosheet machine publicly available. Researchers and enthusiasts can access the project’s blog post for a comprehensive overview, while the design specifics are meticulously documented on GitHub. This open-source approach empowers others to replicate and adapt the machine to suit their specific research needs.
Bonus: The Ripple Effect of Innovation
The story of the DIY nanosheet machine serves as a reminder that necessity can indeed breed innovation. The ingenuity displayed by Mojsoska, Klust, and Thorning has not only addressed a specific problem but has also opened up new possibilities for researchers worldwide. The availability of a low-cost nanosheet machine could accelerate research in this promising field, leading to advancements in antibacterial coatings and potentially improving healthcare outcomes.
This inspiring tale underscores the transformative power of collaboration, resourcefulness, and the democratization of scientific knowledge. It is a testament to the human spirit’s ability to overcome challenges and create solutions that benefit not only the individual but also the broader scientific community.
