Here we consider performance requirements for a thermal cycling device used for diagnostic testing based on the polymerase chain reaction (PCR). These devices are used to exponentially \"amplify\" segments of DNA that may be present in biological samples. These devices are ubiquitous in modern biology laboraties and medical testing services.\n", "\n", "In this notebook we will review:\n", "\n", "* Polymerase chain reaction (PCR) \n", "* Several PCR thermal cyclers used in diagnostic laboratories\n", "* Performance requirements for temperature control in a PCR thermal cycler\n", "* Use of Temperature Control Laboratory to prototype a PCR control system\n", "\n", "The learning goals are for student to able to:\n", "\n", "* Describe use the of feedback control as an enabling technology for laboratory and process systems.\n", "* Develop control performance requirements for an application." ] }, { "cell_type": "markdown", "metadata": { "colab_type": "text", "id": "2IaCjA9tN9gy" }, "source": [ "## Pre-reads\n", "\n", "* [Notre Dame Center for Advanced Diagnostics and Therapeutics](https://advanceddiagnostics.nd.edu/assets/382241/coronavirus_test_faq.pdf)\n", "* [miniPCR Thermal Cycler]( https://www.youtube.com/watch?time_continue=1&v=ALNZJhUOSMs&feature=emb_logo)" ] }, { "cell_type": "markdown", "metadata": { "colab_type": "text", "id": "ta4O_dtbaBah" }, "source": [ "## Coronavirus Diagnostics\n", "\n", "COVID-19 is a respiratory tract infection by a specific species of coronavirus called SARS-CoV-2.
