PolystyreneMicrosphere: Microspheres are small spherical particles, with diameters in the micrometer range (typically 1 μm to 1000 μm (1 mm)). Microspheres are sometimes referred to as microparticles.Surface modification: Surface modification is the act of modifying the surface of a material by bringing physical, chemical or biological characteristics different from the ones originally found on the surface of a material.Latex beads: Latex beads are the polymeric particles suspended in a latex.BiofilmCoulter counter: 150px|thumb|right|The tip of the Coulter counter in a buffer solution, counting cells in solution.AdsorptionGentamicin protection assay: The gentamicin protection assay or survival assay or invasion assay is a method used in microbiology. It is used to quantify the ability of pathogenic bacteria to invade eukaryotic cells.Nanoparticle: Nanoparticles are particles between 1 and 100 nanometers in size. In nanotechnology, a particle is defined as a small object that behaves as a whole unit with respect to its transport and properties.Cell adhesionLipofectamine: Lipofectamine or Lipofectamine 2000 is a common transfection reagent, produced and sold by Invitrogen, used in molecular and cellular biology. Invitrogen (2012).Borosilicate glass: Borosilicate glass is a type of glass with silica and boron trioxide as the main glass-forming constituents. Borosilicate glasses are known for having very low coefficients of thermal expansion (~3 × 10−6 /°C at 20 °C), making them resistant to thermal shock, more so than any other common glass.Soft lithography: In technology, soft lithography refers to a family of techniques for fabricating or replicating structures using "elastomeric stamps, molds, and conformable photomasks".In the words of Rogers and Nuzzo, p.StyreneSociety of the Plastics IndustrySelf-cleaning glass: Self-cleaning glass is a specific type of glass with a surface that keeps itself free of dirt and grime.Polymer blend: A polymer blend or polymer mixture is a member of a class of materials analogous to metal alloys, in which at least two polymers are blended together to create a new material with different physical properties.
