Reagent Integration

Microfluidic equipment has an important role in narrowing the scale of chemistry and biochemical reactions, making it faster, better, and more efficient. Microfluidic lab-on-chip equipment usually requires reagent integration. The reagent required to pre-installed the device can simplify the use process and reduce the processing step and the error associated with the user because the amount and composition of the reagent have been determined.

Alfa Chemistry provides the latest methods and strategies that integrate various types of reagents into the internal interior of the microfluid. We use a number of methods for integrating and releasing the reagent, involving reagents in drying and liquid form, direct integrated reagents or reagents, active agents, as well as passive and mixed release methods.

If you are interested in the integration of our product reagents, we will be happy to provide suggestions.

What we can provide

  • Immobilization of reagents in microfluidic devices

Due to the high surface volume ratio, the microfluidic devices facilitate surface-based reactions. Such reactions typically employ chemical ligands, antibodies, enzymes, or catalysts that are fixed to the surface and react with molecules in the solution. We offer the following two methods of fixed reagents:

  • On-chip storage in dried or liquid form

We usually store the reagents in a dry form on the chip, which will be reconstituted during the measurement process. One of the benefits is that the shelf life of the product can be extended. The most common method of dispensing reagents on a substrate is by spotting the reagent array and then drying it. Reagents can also be stored in liquid form. In these cases, the liquid is mostly contained in an integrated blister.

  • Integrated liquid reagent storage

We use a thin sealed blister that can be integrated into the chip to store one or more liquid reagents or buffers on the chip. Under the action of simple finger pressure or force exerted by a mechanical system, the blister releases an accurate volume of reagent or buffer.
