|Title:||Microfluidic Method for Thermal Cycling by Microwave Dielectric Heating|
|Published:||November 09, 2006|
|Abstract:||We report on temperature time domain and spectral measurements for on-chip microwave thermocycling. In particular we observe enhanced specificity of the heating of a targeted sample compared to conventional heating block-based thermocyclers. Spatial control of the temperature in the device is implemented by delivering microwave energy to specific locations in the microfluidic chip. Our device characterization shows a linear response between the rise in temperature and the applied power as predicted by theory. On-chip thermocycling by microwave dielectric heating is characterized and compared to a commercial heating block-based thermocycler. This method is applicable to any reaction where fast and accurate heat transfer is required. We are currently developing PCR-based applications based on this technique.|
