The invention provides systems, including apparatus, methods, and kits, for the microfluidic manipulation and / or detection of particles, such as cells and / or beads. The invention provides systems, including apparatus, methods, and kits, for the microfluidic manipulation and / or analysis of particles, such as cells, viruses, organelles, beads, and / or vesicles. The invention also provides microfluidic mechanisms for carrying out these manipulations and analysis. These mechanisms may enable controlled input, movement / positioning, retention / localization, treatment, measurement, release, and / or output of particles. Furthermore, these mechanisms may be combined in any suitable order and / or employed for any suitable number of times within a system. Accordingly, these combinations may allow particles to be sorted, cultured, mixed, treated, and / or assayed, among others, as single particles, mixed groups of particles, arrays of particles, heterogeneous particle sets, and / or homogeneous particle sets, among others, in series and / or in parallel. In addition, these combinations may enable microfluidic systems to be reused. Furthermore, these combinations may allow the response of particles to treatment to be measured on a shorter time scale than was previously possible. Therefore, systems of the invention may allow a broad range of cell and particle assays, such as drug screens, cell characterizations, research studies, and / or clinical analysis, among others, to be scaled down to microfluidic size. Such scaled-down assays may use less sample and reagent, may be less labor intensive, and / or may be more informative than comparable macrofluidic assays.

The invention relates to a multi-component composite eccentric fiber. The fiber is a skin-core type composite fiber with an eccentric structure spun by using different components for the skin layer and the core layer. The skin layer component is PA6 and modified PA6, and the core layer is PA6. The layer component is a two-component mixed component composed of PP component and modified PP or EVA component; or the core layer component is a three-component mixed component composed of PP component, low melting point PA6 component and modified PP or EVA component . A method for preparing multi-component composite eccentric fibers. After drying the two components of the skin layer component and the core layer separately, the skin layer component and the core layer component are respectively melted and mixed by a screw, and then enter the eccentric skin-core composite spinning assembly After spinning and winding, multi-component composite eccentric fibers are obtained. The invention solves the problem of poor compatibility between the skin layer and the core layer in the eccentric sheath-core composite fiber, and obtains a composite fiber capable of producing permanent crimp elasticity. The post-processing and dyeing is simple, the obtained fabric is light and soft, and the production cost of the fabric is reduced. At the same time, it can save energy and reduce sewage discharge.
