Hardware


The hardware group of XJTLU-CHINA provides an innovative idea for a small filter device to the iGEM community, which adopts a composite design mode and MBBR technology (Moving-Bed Biofilm Reactor, MBBR). The hardware is divided into two major modules: the coarse filtration system and the biological filtration system. These two modules are connected via magnetic suction devices, facilitating easy assembly and disassembly. Compared to the traditional cylindrical structure of MBBR, we introduce a more interesting structure for hardware manufacturing in the iGEM community—minimal surfaces: Minimal surface structures are a type of porous or grid-like material architecture designed based on mathematical surfaces with zero mean curvature (such as soap bubble surfaces), achieving efficient space filling by minimizing local area. The advantages of this structure include being lightweight yet high in strength, with uniform stress distribution that enhances durability; excellent porosity that benefits heat exchange, fluid transmission, and energy absorption. Minimal surfaces can be classified according to their topological structure, finiteness, or periodicity, and these surfaces can often be realized through 3D printing or computer modeling. In engineering applications, they emphasize a high surface area-to-volume ratio (SAVR) and fluid dynamics optimization. At the same time, we have ummarized a transferability table for triply periodic minimal surfaces, for future iGEM teams to reference and put into practice. Our sand diversion device draws inspiration from the ancient Chinese water conservancy project—Dujiangyan, and we hope that our sand diversion device can provide effective solutions for the iGEM community when facing hardware challenges in solid matter separation. In addition, our filter device can not only be used for the adsorption of Ulva spores but also, through improvements, applied to wastewater treatment, factory production, and other fields, offering innovative ideas for future iGEM projects.

Jiangsu-Zhejiang-Shanghai iGEM Exchange Meeting — XJTLU-CHINA Team

To further promote project exchange and collaboration among universities in the Jiangsu, Zhejiang, and Shanghai regions, the XJTLU-CHINA team successfully hosted the inaugural Jiangsu-Zhejiang-Shanghai iGEM Exchange Meeting. This event aimed to provide regional iGEM teams with a platform for face-to-face communication, experience sharing, and discussion of research practices. As the first school to organize such an event in the region, this exchange meeting not only pioneered a new model for regional collaboration but also laid the foundation for ongoing annual interactions.

The exchange meeting consisted of three main sessions:

  1. Guest Talks – Experts and outstanding iGEM team members were invited to share their experiences, providing valuable guidance on research methods, team management, and science communication, inspiring participants’ thinking and creativity.
  2. Project Presentations – Participating teams presented their iGEM projects, introducing their research ideas, experimental designs, and achieved results. Face-to-face interactions allowed teams to learn from each other and receive constructive feedback.
  3. Project Market & Team Interaction – An interactive session where team members could freely discuss, exchange ideas, and explore potential collaborations. The project market format lowered the barrier to communication and strengthened connections and collaboration among teams.

Through this exchange meeting, the XJTLU-CHINA team established the first regional platform for iGEM team interactions in Jiangsu, Zhejiang, and Shanghai, while also creating a framework and experience for hosting similar events annually. Looking ahead, this exchange meeting is expected to become an important annual event for iGEM teams in the region, continuously promoting the development of synthetic biology education and research, enhancing team connections and collaboration, and fostering a more active and sustainable iGEM community.

Synthetic Biology Exchange Platform

The Human Practice Group of XJTLU-CHINA team has designed and implemented an online synthetic biology community platform, aiming to provide the iGEM community with a digital infrastructure for global communication, education, and collaboration.

The platform is composed of two core modules:

  1. Open Discussion Zone – A public chat area where participants from different regions and cultural backgrounds can freely exchange ideas, ask questions, and engage in interdisciplinary discussions on synthetic biology. This open communication space lowers the barrier for knowledge sharing, encourages inclusivity, and strengthens the collaborative spirit of the iGEM community.
  2. Event Management System – A module where users can create, publish, and manage events (such as education workshops, lectures, or research practices), as well as join activities organized by others. This feature allows synthetic biology education and outreach to transcend geographical limits, fostering a worldwide network of science popularization and collaborative practice.
  3. Through these two components, our platform not only supports real-time communication but also extends the impact of synthetic biology education and public engagement to a global scale. By combining accessibility, scalability, and interactivity, the platform provides the iGEM community with a methodological framework for organizing, disseminating, and participating in outreach activities.

    Looking forward, this contribution offers future iGEM teams a replicable model of digital collaboration and co-creative education design, enabling them to enhance their education efforts, connect across borders, and cultivate a more interactive and sustainable synthetic biology community.
