Learning Objectives: Students should leave this unit equipped with a theoretical understanding of how to '''detect DNA biomarkers''' and the relevance of this technology to human healthcare. Emphasis will be on good lab/experimental controls and the collection of statistically valid measurements. Students will also understand how commonly used lab devices function, and explore the recent efforts to simplify experiments and to lower costs. At the end of the section, students will explore creative new biosensor designs based on PCR and fluorescent imaging. | Learning Objectives: Students should leave this unit equipped with a theoretical understanding of how to '''detect DNA biomarkers''' and the relevance of this technology to human healthcare.

Introduction to Biomedical Engineering
GETTING STARTED
THE COURSE IN REVIEWSet-up: OpenPCR BuildingBefore this unit began, a group of ~10 upper level undergrads and graduate students assembled the OpenPCR machines. This was a great experience for the graduate students, and saved our Freshmen engineers the time and trouble of assembling the delicate pieces from scratch in a very limited amount of time. Thanks to our assembly team and Dr. Pizziconi's Design Studio team for your help!
Week 1: Introduction - DNA as a Biomarker, 10/17/12Students were introduced to basic DNA science and its relationship to diagnostics and health. Sequence-specific DNA hybridization uses primers designed to base-pair with a target disease-associated marker. This leads to exponential amplification of an invisible DNA target. A mismatch (non-disease DNA sequence) does not produce amplification. Team members chose roles as Open PCR machine tester/ engineer, Experimental protocol planner, and Research and development scientist.
In concurrent work sessions...
Week 2: DNA Amplification Reactions, 10/24/12Students used their experience from the previous week to set up and run a PCR experiment. The students were provided with personal protective equipment, 8 tubes of 50 μL PCR reaction mix, 8 tubes of 50 μL diluted template + primers, and disposable transfer pipettes. The instructors provided positive and negative "patient" samples so that some samples would test positive for a DNA marker (produce amplification), and others would test negative (no amplification).
Activities:
Students were introduced to a Single Drop Fluorimeter fluorescence-based DNA detection device that was designed by Dr. Garcia. When a natural or PCR-amplified double-stranded DNA sample is stained with SYBR green and exposed to a blue LED light, the drop fluoresces green. The signal is captured as an image with the user's camera phone.
Week 3: Computer-Aided Design with SolidWorks, 10/31/12Activities:
Week 4: Measuring DNA Using Fluorescence, 11/7/12
Lab Report 1: Each team created a Wiki page write-up of their learning experiences.
Week 5: Designing a New System, 11/14/12Activities:
Week 6 & 7: Advertisement Videos, 11/28/12 & 12/6/12Activities:
