Week 3 HW: LAB Automation

Post-Lab Question 1

A study by the Opentrons research community demonstrated how low-cost laboratory automation platforms can accelerate biological experiments. The researchers used the Opentrons OT-2 robot to automate liquid handling tasks such as pipetting, reagent mixing, and plate preparation.

In the study, the robot was programmed using Python scripts to perform repetitive experimental steps with high precision. Automation enabled researchers to run multiple biological assays simultaneously while reducing human error.

The key innovation of this approach is that Opentrons is an open-source system. Scientists can modify the protocol, integrate custom labware, and automate workflows such as PCR setup, enzyme assays, and high-throughput screening. This significantly lowers the barrier to entry for laboratory automation and enables more scalable experimental design.

Post-Lab Question 2

Project Idea: Automated PCR Reaction Setup

For my final project, I plan to automate the preparation of PCR reactions for testing multiple DNA samples.

The workflow would involve:

1. The Opentrons robot distributing PCR master mix into all wells of a 96-well plate.

2. The robot adding different DNA templates into each well.

3. Mixing the reactions automatically.

4. Preparing the plate for thermocycling.

Automation would allow dozens of PCR reactions to be prepared quickly and reproducibly. This approach could be integrated with bioinformatics workflows where DNA sequences are designed computationally and then experimentally tested.
