PART 1Executive Overview
1Definition

Liquid biopsies are non-invasive tests that analyze circulating tumor cells (CTCs) and cell-free DNA (cfDNA) fragments found in the bloodstream. These tests can provide insights into the presence, type, and progression of cancer without requiring a traditional tissue biopsy.

2Problem It Solves

Traditional tissue biopsies are invasive, painful, and sometimes difficult to obtain. Liquid biopsies offer a non-invasive alternative that can be performed repeatedly over time, providing continuous monitoring of the patient's condition without additional invasiveness.

PART 2Technical & Manufacturing
4How It Works

Advanced sequencing technologies, such as next-generation sequencing (NGS), are employed to identify specific genetic markers or mutations present in CTCs and cfDNA. By analyzing these genetic signatures, clinicians can detect the presence of cancer, monitor disease progression, and even predict treatment response.

5Materials Used
6Manufacturing / Creation Process

The manufacturing process involves developing and validating assays for CTC capture and cfDNA extraction from blood samples. This includes optimizing cell isolation techniques, ensuring accurate sequencing, and creating robust bioinformatics pipelines to interpret results.

7Build Process

The build process typically starts with the development of specialized microfluidic devices or magnetic beads for capturing CTCs. These are then integrated into a larger system that processes multiple samples simultaneously. The cfDNA is extracted using enzymatic digestion followed by purification steps, and both CTCs and cfDNA are sequenced using NGS platforms.
