Multi-scale manipulation refers to manipulation of objects with operational length scales ranging from several millimeters to nanometers. An optoelectric platform, which integrates multiple physical mechanisms, uses optically triggered electrokinetics to achieve multi-scale manipulation. These platforms are characterized by dynamic programmability and multi-tasking.


The growing demand for point-of-care analysis has motivated the rapid growth of the lab-on-a-chip (LoC) market. Considering the complexity, diversity, and multitasking nature of the technology, considerable efforts have been made to create a versatile platform capable of handling as many targets as possible. Multi-scale manipulation, or the ability to manipulate media and particles at multiple length scales, has been a significant and sought-out milestone in the LoC field for years. Despite the rapid progress over the past decade in...
