Biology & Biomedical
Effective biological and biomedical research requires specific control of the cellular microenvironment and biomaterial characteristics. Plasma treatment cleans and activates the surfaces of biomaterials through the introduction of functional groups without affecting the bulk. Increased hydrophilicity or hydrophobicity of material surfaces increase the adhesion, coverage and proliferation of cells or induce the formation of spheroids respectively. In addition, plasma treatment has been shown to improve biocompatibility characteristics for numerous applications. As a result plasma treatments is used extensively for cell seeding, protein adsorption, biomaterial coating and implant surface activation. This page contains brief application summaries and relevant articles concerning the use of plasma treatment in biological and biomedical research.
