Optimisation of Polymer Particles Propulsion on Caesium Ion-exchanged Channel Waveguide for Stem Cells Sorting Applications
Optical trapping of particles has become a powerful non-mechanical and non-destructive technique for precise particle positioning. The manipulation of particles in the evanescent field of a channel waveguide potentially allows for sorting and trapping of several particles and cells simultaneously. This paper describes the studies carried out, both theoretically and experimentally, to optimise t...
متن کاملOptimized Digital Optical Switch Using Proton Exchanged Lithium Niobate Waveguides
The main emphasis in developing DOS has been on achieving low crosstalk (CT). CT in the order of -30 dB is acceptable in conventional DOS and below that value is hard to achieve. Relatively low drive voltage (or power requirements) is also necessary to optimized DOS. This paper depicts the design of Y-branched digital optical switches (DOS) with optimized on-chip area coverage, reduced driving ...
متن کاملPreparation, characterization and antimicrobial property of ag+- nano Chitosan/ZSM-5: novel Hybrid Biocomposites
Objective(s): Binary hybrids of chitosan-zeolite have many interesting applications in separation and bacteriostatic activity. Materials and Methods: Template free ZSM-5 zeolite was synthesized by hydrothermal method, physical hydrogels of nano chitosan in the colloidal domain were obtained in the absence of toxic organic solvent and then nano chitosan/ZSM-5 hybrid composites with nano chitosan...
متن کاملPoly (lactic-co-glycolic)/nanostructured merwinite porous composites for bone tissue engineering: II. structural and in vitro characterization
Several characteristics of a novel PLGA/Merwinite scaffold were examined in the present study to evaluate the possible applications in bone tissue regeneration. Physical and mechanical properties, as well as degradation behavior and in vitro bioactivity of porous scaffolds produced by solvent casting and particle leaching technique were also characterized. Results showed that incorporation of m...
متن کاملTwo-step K(+)-Na+ and Ag(+)-Na+ ion-exchanged glass waveguides for C-band applications.
A two-step K(+)-Na+ and Ag(+)-Na+ ion-exchange technique is introduced to fabricate single-mode channel waveguides in BK7 glass for the telecom-wavelength region. The dependencies of insertion loss, polarization-dependent loss (PDL), end bending loss of curved waveguides on channel width, diffusion time, and annealing time are investigated. Results show that postannealing is a required process ...
