Summary
Early dengue diagnosis is crucial for controlling epidemics and preventing severe illness. This study reviews current and advanced diagnostic methods, including novel nanosensor technologies for rapid, point-of-care detection.
Area of Science:
- Medical Diagnostics
- Infectious Diseases
- Nanotechnology
Background:
- Dengue fever is a global infectious disease with recurring, potentially fatal epidemics.
- Effective disease control necessitates rapid and specific diagnostic tools for early detection.
- Timely diagnosis prevents complications and aids management during outbreaks.
Purpose of the Study:
- To review current and advanced diagnostic methods for dengue infection.
- To discuss the analytical performance and clinical applicability of these methods.
- To explore emerging technologies for point-of-care dengue diagnostics.
Main Methods:
- Enzyme-linked immunosorbent assay (ELISA)
- Reverse transcriptase polymerase chain reaction (RT-PCR)
- Advanced instrumental techniques (QCM, SPR, photonic crystals, EIS)
- Nanosized materials (liposomes, nanowires, nanopores) coupled with detection methods (fluorescence, potentiometry, voltammetry)
Main Results:
- Conventional methods like ELISA and RT-PCR are discussed.
- Instrumental methods show promising diagnostic potential.
- Nanosensor technologies offer innovative approaches for dengue detection.
Conclusions:
- A range of diagnostic methods exist for dengue infection.
- Advanced instrumental and nanosensor-based techniques offer improved sensitivity and speed.
- Future developments aim for inexpensive, point-of-care diagnostics for epidemic situations.
