Proteins and ligands adsorb onto polystyrene readily and permanently, which makes polystyrene microspheres suitable for medical research and biological laboratory experiments.
A few microliters of microspheres could contain thousands of array elements and each array element is represented by hundreds of individual microspheres.
He found that, as they dried, the amino acids formed long, often cross-linked, thread-like, submicroscopic polypeptide molecules now named proteinoid microspheres.
