Biochips, or microarrays, enable rapid, simultaneous analysis of thousands of biological reactions, like gene expression. While promising for cancer diagnostics, challenges in bioinformatics and standardization must be overcome for routine clinical use.

Area of Science:

  • Biotechnology
  • Molecular Biology
  • Genomics

Background:

  • Biochips (microarrays) are solid substrates with high-density biomolecule attachments.
  • They enable high-throughput analysis of biological reactions, akin to computer chips for data processing.
  • Key applications include genomics, proteomics, glycomics, pharmacology, and toxicology.

Purpose of the Study:

  • To provide an overview of biochip technologies and applications.
  • To discuss the potential of microarrays in determining gene expression, particularly in cancer.
  • To highlight limitations, challenges, and future developments for clinical integration.

Main Methods:

  • Review of current biochip technologies and their applications.
  • Discussion of gene expression analysis using microarrays for disease research.
