In the last decade, there is a great interest in analytical miniaturized systems on microchips, and on chip integrated systems for different chemical processes like mixing, reactions and detection are on rapid progress.

The advantage of miniaturized integrated systems include less sample volume and reagent consumption, more effective reaction because of the large ratio of surface-to-volume and lower cost. It also permits a rapid and efficient mixing as well as the recording of continuous IR spectra. These benefits lead the microchip technology to the various applications like flow control, chemical analysis, biomedical diagnostics, drug discovery, inkjet printers, biochemical assays, genetic analysis, drug screening, electrochromatography.

Antithyroid drug measurement in microfluidic chip-PTLM

Determination of MMI Methimazole (1-methyl-2-mercaptoimidazole) (MMI) using glass microfluidic chip-photo thermal lens microscopy (MFC-PTLM) in human serum and pharmaceutical samples. Both MMI and gold nanoparticles (GNPs) solution were introduced at the same flow rate (200 μL/min) to the microchannels by two microfluidic syringe pumps VIT-FIT.

Protein conformation states studied using microfluidic mixer

Commercial Fourier-transform infrared (FTIR) spectrometer was coupled to a microfluidic mixer to allow the on-line monitoring of protein conformation under varying conditions. Two VIT-FIT programmable microfluidic syringe pumps were used to deliver the protein and NaOH solutions to microfluidic mixer with two inlets, at slow flow rates (10 arb. units).
