Point-of-Care (POC) Micro Biochip for Cancer Diagnostics

Nunna B.B., Lee E-S, New Jersey Institute of Technology, US

American cancer society stated that a total of 1,685,210 new cancer diagnosed cases out of which 595,690 deaths from cancer are expected to be reported in the United States of America in 2016. Unfortunately Cancer [...]

Effects of Solvents on Dissolution of Photoresist in Parylene Microchannels

Ceylan Koydemir H., Kulah H., Ozgen C., Tosun I., Middle East Technical University, TR

This paper presents a detailed study for the effects of different types of solvents on dissolution of photoresist inside the parylene micro-channels, for the first time. Experimental results indicate that photoresist dissolution in dipolar aprotic [...]

Two-Phase Convective Heat Transfer in Microchannels

Lin C.Y., Hsieh S.-S., Chen J.H., National Sun Yat-Sen University, TW

Experiments were conducted to investigate subcooling flow boiling in 75 parallel microchannels (L=30 mm) having 200 μm (W) x 100 μm (H) cross-section with/without structured reentrant angle ( 0°、60°、90°and 120°). Boiling inceptions, flow morphologies, critical [...]

Study on fluorescent detection glucose molecule marked with ZnSe nano crystalline in microchannels

Bai Z-C, Qin S-J, Guizhou University, CN

Single molecule detection has been a hot point problem of science and research, classic dye fluorescent marking technology has a many defects, for example fluorescent power low, fluorescent instability , and so on. Fluorescent quantum [...]

Heat Transfer Cost-Effectiveness of Nanofluids

Xu D., Pan L., Yao Q., Institute og High Performance Computing, SG

When metal or oxide nano particles are dispersed in fluids to form nanofluids, the particles will improve the thermal conductivity of the fluids. Therefore, it is suggested to use nanofluids as coolant to improve heat-exchanger [...]

Numerical and Experimental Investigation of Three-Dimensional Hydrodynamic Focusing in Polydimethylsiloxane (PDMS) Microchannels

Chang C-C, Yang R-J, National Cheng Kung University, TW

In this work, we have designed and fabricated a three-dimensional hydrodynamic focusing microfluidic device, as shown in Figure 1. The design of the device is modified from that of a previous study [1], which comprises [...]

Microchannel Immunoassays with Electrochemical Detection in Devices Constructed from Low Temperature Co-fired Ceramic and Screen Printed Gold

Fakunle E.S.O., Fritsch I., University of Arkansas, US

We report the first self-contained electrochemical enzyme linked immunosorbent assay in microchannel devices constructed from low temperature co-fired ceramic (LTCC) with screen-printed gold for fast and sensitive assays. No one has previously reported a device [...]

A Vertical MOSFET for Charge Sensing in the Convex Corner of Si Microchannels

Lim G., Park C-S, Lyu H-K, Kim D.S., Shin J-K, Choi P., Lee M., Kyungpook National University, KP

In this paper, we will present a vertical MOSFET formed in the convex corner of silicon microchannels which might be useful for detecting charged biomolecules. The cross type microchannels have four MOSFETs and four pairs [...]

Quasi-static Motion of Bubbles in Microchannel Contractions

Jensen M.J., Goranovic G., Bruus H., Technical University of Denmark, DK

We present a thorough theoretical and computational study of bubble dynamics in icrofluidic channels with contractions. We investigate the effects of geometry and surface physics (friction and contact angle) on the behavior of incompressible bubbles, [...]
