Targeting of MCF-7 Breast Cancer Cells using MTBs
We investigate the sensing capabilities of magnetotactic bacteria (Magnetospirillum gryphiswaldense strain MSR-1) toMCF-7 breast cancer cells. Microfluidic chips with a three-way junction are designed and fabricated. These chipscontains one inlet and two chambers to insert the bacteria and to contain the cancer cells, respectively.
ObjectiveIn this project, we will do experiment using magnetotacticbacteria (MTBs), fluidic microchips with three-wayjunction, and cancer cells. The ultimate goal of theexperiment is to investigate the sensing capabilities ofMTBs to cancer cells. MTBs have long been known toswim towards environment with relatively low oxygencontent. Cancer cells influence the oxygen gradient locally,and therefore we expect that MTBs will swim towards thecells.
Tasks• Development of a feature tracking algorithm to count
the number of MTBs that swim through the three-wayjunction Fig. 1;
• Tracking of multiple bacteria to provide quantitativeinformation on the culture;
• Collecting experimental data to investigate the sensingcapabilities of the MTBs to the cancer cells.
Materials• 4 electromagnetic coils are available in MNRLab;
• 4 electric drivers;
• Motion control systems;
• A microfluidic chip with three-way junction;
• MCF-7 breast cancer cells.
PREREQUISITESStudents are expected to have a working knowledgeof control theory, differential equations, linear systems,statics, kinematic and dynamics. Familiarity withprogramming, especially with Matlab and C++.
OTHER NOTESThis project will involve a weekly meeting with theinstructors and progress reports have to be prepared. Allreports should be written in academic paper format.

Figure 1. Magnetotactic bacteria (MTB) are inserted in the fluidicchip to select between the left and right chambers. (a) Thethree-way junction allows us to observe the motion of the MTBtowards the left and the right chambers. (b) A few hundreds ofMTB are observed in the channel connected to the chamber ofthe MCF-7 breast cancer cells. (c) A few MTB are observed alongthe channel connected to the chamber of the cancer cell medium.(d) The left chamber contains cancer cells. (e) The right chambercontains cancer cell medium only.
