This invention generally relates to an integrated lab-on-a-Pipette™ which will provide sample-to-answer single cell genetic diagnosis for preimplantation genetic diagnosis (PGD) and other forms of single cell analysis (SCA). SCA is a quickly growing field with substantial impact in prenatal testing, cancer biopsies, diabetes, stem cell research, and our overall understanding of heterogeneity in biology. However, single cell genetic analysis is challenging, inaccurate, and in many cases impossible, due to the small amount of sample (5 pg), and difficulties in handling small sample volumes (50-100 pL). The lab-on-a-pipette device integrates a microaspiration tip with microfluidic analysis components to conduct in-situ, real-time single cell genetic diagnosis in a single device. The microaspiration tip extracts and encapsulate a cell into an ultra-low volume plug (˜300 pL). |
