Aptamer-based rapid diagnosis for point-of-care application

Area of Science:

• Biomedical Engineering
• Analytical Chemistry
• Molecular Diagnostics

Background:

• Point-of-care testing (POCT) aims to reduce diagnostic and treatment times compared to centralized facilities.
• Aptamer-based biosensors offer advantages over traditional antibody or enzyme-based sensors for disease detection.
• The need for rapid, accessible diagnostics is critical, especially during epidemics.

Purpose of the Study:

• To review design strategies and virus detection methods using aptamer-based sensors.
• To discuss the principles and importance of aptamers in biosensing.
• To highlight the advantages of aptasensors for point-of-care (POC) applications.

Main Methods:

• Comprehensive literature review of aptasensor design and applications.
• Analysis of aptamer selection and detection principles.
• Classification of POC aptasensor diagnostic applications for infectious and non-infectious diseases.

Main Results:

• Aptasensors provide sensitive, specific, and flexible detection methods for rapid diagnostics.
• POC aptasensors are crucial for early disease detection, epidemic control, and reducing healthcare burdens.
• Various design factors are outlined for developing future rapid POC aptasensors.

Conclusions:

• Aptasensors are highly promising for advancing point-of-care diagnostics.
• Further development of aptasensor technology will enhance disease management and public health.
• Optimized aptasensor designs are key to meeting the demand for fast, reliable POC testing.
