In our first on-site visit, we designed and fabricated a microfluidic device with specific parameters fit to trapping the MIT team's mammalian HEK293 cells. Our first iteration of chip included an input, cell traps surrounded by two valves, and an output, as shown. We automated the control of the valves using our servo-syringe combination pumps. To prepare the chip for the cells, first, we opened our valves to flow 1.2mL of ethanol solution inside the chip for sterilization. Next, we pulled 1mL of PBS (buffer solution) to clean out the ethanol solution for the benefit of the cells. Finally, we pulled 1ml of cell solution with a concentration of 1 x 10^6 cells/ml through the microfluidic chip. The two valves were then closed (trapping the cells and culture media inside) and the chip removed from the control infrastructure. From there, we observed masses of cells moving in the sealed area of the chip under a standard light microscope at 10x, as shown. Finally, we relocated the chip an incubator to grow the cells.

This visit proved our fabrication flow's ability to create microfluidic devices capable of trapping HEK293 mammalian cells, and gave both teams great insight on the other end of the biologist-microfluidics bridge, and sparked ideas for further customization of microfluidics for the lab bench.

COLLABORATIONS
NEPTUNE Collaborative Findings
Given that Neptune was built to provide an accessible, affordable, and convenient solution for designing, manufacturing, and operating microfluidic systems, it was only natural that we would test our toolchain by designing microfluidics for other iGEM wetlab teams. We were able to collaborate with both the MIT iGEM team and the Northeastern iGEM team. Through these exchanges, we were able to test the Neptune workflow while providing a wetlab team with microfluidics to test their biological systems.
Building an Estrogen Concentration Control Chip
SEPT - OCT 2016 | A collaboration with the MIT 2016 iGEM Wetlab Team
Our collaboration with the MIT iGEM team involved designing, creating, and controlling microfluidic devices to culture mammalian cells on chip. The end goal of these experiments was to lay the groundwork for testing endometrial cell lines and their response to various levels of estrogen in an automated microfluidic setting.
PART 1
In our first on-site visit, we designed and fabricated a microfluidic device with specific parameters fit to trapping the MIT team's mammalian HEK293 cells. Our first iteration of chip included an input, cell traps surrounded by two valves, and an output, as shown. We automated the control of the valves using our servo-syringe combination pumps. To prepare the chip for the cells, first, we opened our valves to flow 1.2mL of ethanol solution inside the chip for sterilization. Next, we pulled 1mL of PBS (buffer solution) to clean out the ethanol solution for the benefit of the cells. Finally, we pulled 1ml of cell solution with a concentration of 1 x 10^6 cells/ml through the microfluidic chip. The two valves were then closed (trapping the cells and culture media inside) and the chip removed from the control infrastructure. From there, we observed masses of cells moving in the sealed area of the chip under a standard light microscope at 10x, as shown. Finally, we relocated the chip an incubator to grow the cells. Unfortunately, the device dried out a day after being placed in the incubator. This visit proved our fabrication flow's ability to create microfluidic devices capable of trapping HEK293 mammalian cells, and gave both teams great insight on the other end of the biologist-microfluidics bridge, and sparked ideas for further customization of microfluidics for the lab bench. Highlighting the rapid design and prototyping enabled with Neptune, not a week later we returned with an entirely new design and batch of two chips ready for further testing (while our design and fabrication flow allows for iterations to occur within hours, the schedule of both teams needed about a week). This further collaboration is detailed below.

Part 2 Content
Designing a Cell Nutrient Starvation Inducer
AUG - SEPT 2016 | A collaboration with the Northeastern 2016 iGEM Wetlab Team
We designed a microfluidic device for Northeastern University's iGEM team to help characterize their starvation-induced genetic part, by flowing cells through a set of cell traps placed after a gradient generator, then flowing two variable amounts of nutrients through the inputs of the gradient generator, causing a variable amount of nutrients to hit each cell trap, and cause a variable expression level of the starvation-linked fluorescence. Unfortunately, due to difficulties on both sides, the device and the cells to put through it were never realized. The preliminary sketches and designs are shown here, however.
Open Source Materials and Synthetic Biology
Open source materials encourage a cooperative and connected community in any field of research. It allows individuals and labs to easily share their ideas for others to build off of and can inspire even greater creations. So we teamed up with the BU 2016 iGEM Wetlab Team to investigate the current place of open source materials in Synthetic biology and how, moving forward, open source materials could impact the direction of the field. We recorded our findings biweekly through posts in a collaborative blog entitled "Who Owns What".
