These tools let us study thousands of DNA sequences at once. They give us deep insights into genes, genetic changes, and disease markers.
Structure and Design of DNA Microarrays
DNA microarrays have a solid base, like glass, silicon, or plastic. On this base, many DNA probes are arranged in a grid. These probes are short DNA sequences that match specific DNA or RNA molecules. This lets us detect and measure many genetic targets at once.
Core Components of Biochip Platforms
- DNA probes: Short, single-stranded DNA sequences complementary to the target genetic material.
- Solid substrate: The surface on which the DNA probes are immobilized, providing a platform for the hybridization process.
- Sample preparation: The pre-processing of the genetic material (DNA or RNA) to be analyzed, often involving labeling with fluorescent dyes.
- Detection system: The hardware and software components that capture, analyze, and interpret the signals generated during the hybridization process.
Probe Selection and Immobilization Techniques
Choosing and fixing DNA probes on the biochip is key for good DNA microarray analysis. Many algorithms and tools help pick the best probes for the genetic sequences we want to study. Methods like photolithography, ink-jet printing, and microfluidic spotting are used to place these probes on the chip. This makes it possible to study many genes at once in DNA chip fabrication.
“The ability to analyze thousands of genes simultaneously has transformed our understanding of biological systems and opened up new avenues for biochip technology applications in personalized medicine and drug discovery.”
