PS Substrates

Polystyrene (PS) is an aromatic polymer made from styrene monomer. It has gained industrial attention due to its good mechanical properties and low cost, and its non-toxicity and high transparency have made it one of the important raw materials in the biomedical field. PS is not only widely used in cell/tissue culture containers, but also has an important application in the preparation of micro- and nano-sized devices, such as microfluidic chips. Its hydrophobic surface can be made hydrophilic by various physical and chemical methods including corona discharge, gas plasma, irradiation, etc., which can enhance its binding with chemical or biological ligands or improve its interactions with biofluids.

Alfa Chemistry offers a range of PS substrates that are well suited for building cell culture microfluidic chips. If you don't find what you are looking for, please contact us. We can provide product customization according to your specific requirements.
