Measuring Bacterial Growth Using A 3d-Printable Spectrometer, Samuel R. Bunting
Measuring Bacterial Growth Using A 3d-Printable Spectrometer, Samuel R. Bunting
Williams Honors College, Honors Research Projects
Visible light spectroscopy is a commonly used technique for measuring the growth of bacterial cultures, and growth curves provide broadly important data. However, the equipment and resources required for these experiments has been restricted to higher education and industry due to high cost and sophistication. We have previously reported on an inexpensive, 3D-printable photospectrometer called the SpecPhone. This device utilizes an iPhone as the camera, along with several other, inexpensive additions to make a fully functional spectrometer. Here, the application of the SpecPhone is expanded to the quantification of actively dividing E. coli cultures. Two protocols have been developed; one …

Spectroscopy is a widely used chemical and medical analysis tool. While spectrophotometers are commonly found in many universities and laboratories, they are not available to all high schools or laboratories in developing countries. The objective of this project was to design a high-quality, 3D-printable, iPhone-compatible spectrophotometer that uses a cell phone camera and interface to collect data. The created 3D-print file will be available to anyone with access to a 3D printer which are increasingly found in many laboratories and schools across the country. A low cost pre-printed kit will also be made for those without access to a 3D …
