Background: The COVID-19 pandemic has significantly affected global health, economies, and societies, and highlighted the urgent need for rapid, sensitive, affordable, and portable diagnostic devices for respiratory diseases, especially in areas with limited resources. In recent years, there has been rapid development in integrated equipments using microfluidic chips and biochemical detection technologies. However, these devices are expensive and complex to operate, showing limited feasibility for in point of care tests (PoCTs).

- On-site bioaerosol monitoring is crucial for assessing microbial levels and reducing infection risks from aerosols, and this study presents a new 3D-printed electrostatic sampler for effective collection.
- The sampler uses charged particles and has been optimized through advanced software simulations to enhance its performance in gathering bioaerosols of varying sizes.
- Test results showed that the sampler can efficiently collect over 90% of particles larger than 1.2 μm under specific conditions (4.7 kV voltage, 2 L/min air), making it a low-cost and portable solution for pathogen detection in different environments.
