Protein biochip systems for the clinical laboratory

Area of Science:

• Biomedical Engineering
• Analytical Chemistry
• Biotechnology

Background:

• Classical protein analysis methods (electrophoresis, ELISA, liquid chromatography) are time-consuming, labor-intensive, and lack high-throughput capacity.
• Existing methods require sample division and individual tests, increasing costs and complexity.
• Multiplexed assays offer a solution by measuring multiple analytes simultaneously from a small sample volume.

Purpose of the Study:

• To review current trends and advances in miniaturized multiplexed immunoassay technologies.
• To focus on chip-based assays applicable to clinical laboratories and biomedical diagnosis.
• To highlight the potential of "lab-on-a-chip" devices for point-of-care testing.

Main Methods:

• Review of emerging technologies in miniaturized multiplexed immunoassays, categorized into spotted array-based and microfluidic-based tools.
• Focus on "lab-on-a-chip" systems combining miniaturization, microfluidics, and nanoparticle technology.
• Evaluation of systems ranging from research applications to point-of-care assays.

Main Results:

• Chip systems allow simultaneous testing of multiple analytes without sample division.
• Miniaturized multiplexed immunoassays yield significant information from minimal sample volumes.
• Recent advances integrate miniaturization, microfluidics, nanoparticles, and quantification for enhanced biochip assays.

Conclusions:
