Article Synopsis
- Micro and nano-scale manipulation of living matter is important for diagnosing diseases, drug development, and identifying biomarkers, but trapping biological nanoparticles has been challenging.*
-
- The study introduces a new inverted hybrid dielectric-plasmonic nanobowtie that addresses issues of high cost and complex manufacturing in current systems while allowing for stable trapping of biological samples with minimal damage.*
-
- Numerical simulations show this innovative design can trap 100 nm viruses with a strong optical force and improved energy confinement, while preserving the biological sample's integrity.*
Article Synopsis
- * A new on-chip platform utilizes a micromixer and microfluidic channel with engineered electrodes to leverage di-electrophoresis for enhanced performance.
- * The innovative system demonstrates over 98% sorting efficiency of live and dead bacteria, operates at low power (1V), and responds in 5 seconds, making it ideal for single-bacterium-level monitoring in future medical applications.
