The on-chip optofluidic technology has emerged as a powerful and efficient tool for on-chip manipulation of particles, biological cells, and biomolecules. Different kinds of optofluidic manipulation chips based on different optical components have been developed to achieve ultrasensitive manipulation of biomolecules. In the point of near-field optofluidic manipulation, Bradley and Erickson developed planar SU-8-based waveguide to trap and transport the biopolymer in the evanescent field [2]. Olav et al. developed an optical waveguide loop to achieve the stable trapping of red blood cells and demonstrate the potentials which can... 

The capabilities in terms of fluidic control, mixing, miniaturization, and optical property tuning afforded by micro-, nano-, and electrofluidics provide an ideal platform upon which to build versatile optofluidic devices. In this entry we provide a general overview of some of the emerging applications of optofluidic technology. Providing a comprehensive overview of all the research in this field is outside the scope of this review. Rather we will provide a number of representative examples of the state of the art... 

Extensive reviews on the development of optofluidic technology (Levy and Shamai, 2008 Monat et al., 2007 Psaltis et al., 2006 Whitesides, 2006) show different examples in a few categories, including fluid-solid, purely fluidic... 

Abstract The self-organized and molecularly smooth surface on liquid microdroplets makes them attractive as optical cavities with very high quality factors. This chapter describes the basic theory of optical modes in spherical droplets. The mechanical properties including vibrational excitation are also described, and their implications for microdroplet resonator technology are discussed. Optofluidic implementations of microdroplet resonators are reviewed with emphasis on the basic optomechanical properties.

The objective of nanoscale optofluidic charac-terizatimi is to combine different nanophotonics technologies with microfluidic devices and thereby explore and develop photonic analysis techniques based oti the microscopic flows of liquids and on nanophotcHiic properties. The optofluidic character-izatimi techniques will be powerful new tools for a wide range of applications in optical information processing and the miniaturizatimi of chemical and biological processes for synthesis, analysis, and recognidOTi [1]. 

One of the most important factors is to diversify the materials constituting optofluidic devices. Physicochemical functionalities of mobile fluids should be exploited to manipulate the optical and fluidic properties of optofluidic devices. Current optofluidic device technology has used a very limited number of materials for mobile and immobile phases of optofluidic devices consequently, the required flexibility has not yet been achieved. As for compatibility with fluidic devices, proper affinity between liquids and substrates poses many challenges to the application of optofluidic characterization devices.
