چکیده
Abstract Smart channels that manipulate liquid motion by anisotropic shape changes represent a promising candidate to construct microfluidics for biochemical analysis. However, the existing systems fail provide platform solid exchange mediums interact with multiple phases, which is universal technique effectively extract, enrich, and precisely detect biomarkers. Herein, combined photo/magnetic control strategy of mixed phase fluids, integrates contactless operations suspending, depositing, even separating, reported first time based on trilayer microtube consisting flexible supporting layer, photodeformable crystal polymer, hydrophilic blocking layer. The asymmetric photodeformation polymer generates an internal vortex in homogenously disperse into various aqueous moving droplets enable efficient purification enrichment target A newly constructed homemade portable protein analyzer guided features advantages short detection (20 min), trace sample consumption (5 μL), low limit (1 μg mL −1 ).

Polymer-stabilized blue-phase liquid crystal grating cured with interfered visible light.
In this paper, we demonstrate a holographic polymer-stabilized blue-phase liquid crystal grating fabricated using a visible laser. As blue phase is stabilized by the interfered light, polymer-concentration gradient is achieved simultaneously. With the application of a uniform vertical electric field, periodic index distribution is obtained due to polymer-concentration gradient. The grating exhi...
متن کاملSubmicron manipulation tools driven by light in a liquid
Optically driven micromanipulators with submicron probe tips are proposed and developed by using two-photon microstereolithography. The micromanipulators are worked by maneuvering their movable component with a focused laser beam, and an actual pair of microtweezers was opened and shut precisely. We also propose an effective method of controlling movable micromachines with great freedom of move...
متن کاملRecent Advances in Polymer Network Liquid Crystal Spatial Light Modulators
Polymer network liquid crystal (PNLC) spatial light modulators are attractive for display and photonic applications because they can achieve submillisecond response time while keeping a large phase change. However, their on-state scattering caused by the grain boundary of LC multidomains hinders their applications. In this article, we review recent progress on the development of scattering-free...
متن کاملElectro-optics of polymer-stabilized blue phase liquid crystal displays
Electro-optics of polymer-stabilized blue phase liquid crystal displays BP LCDs is analyzed and validated experimentally. A numerical model for characterizing and optimizing the electro-optical and display properties of BP LCDs in in-plane switching and fringe field switching cells is developed. The simulated voltage-dependent transmittance curves agree well with the measured results. To lower ...
