AnaChips™ for Surface Science Applications

Surface Science and thin film applications are studied on AnaLight® instruments by injecting one or more molecular species into the flow over the prepared surface of an AnaChip™, often with another interacting molecule already immobilised. Molecular immobilisation onto the AnaChip™ surface can be undertaken by either covalent chemistry or charge (physisorption).

Farfield offers a range of AnaChips™ suitable for surface science and Nanotechnology applications. The most suitable AnaChip™ surface for any experiment should be assessed according to the properties of the molecules being studied and the objectives behind the measurements being taken on the AnaLight®.

Surface: Uniform coating of unmodified, dissolving pulp cellulose. Spin coated from NMMO-DMSO solution to give a 17nm thin cellulose surface film. Mimetic surface for cotton-based fabrics and paper. Stable across a range of pH and no loss of surface material in surfactant solution.

Use: Suitable for fabric care cleaning and conditioning formulation development, paper coating technology and ink formulation studies and pharmaceutical formulation research and development.

Ordering information: Part No. 2007-211c (pack of 5)

Surface: Unmodified silicon oxynitride giving hydroxyl surface chemistry carrying negative charge. Positively charged molecules can be immobilised to the surface by physisorption. Hydroxyl surface chemistry is also available for customer-defined covalent immobilisations using silane chemistry with or without linkers.

Use: Suitable for study of surfactants, polymers, proteins, oils & fats, carbohydrates, and lipids

Ordering information: Part No. 2007-110c (pack of 5)

Unmodified AnaChip™ (as above) additionally supplied with Manufacturers Test Certificate guaranteeing specifications and traceability. For use in AnaLight® Qualification Procedures and validatied applications, where traceability to national and international standards is required.

Ordering information: Part No. 2007-162c (pack of 1)

Surface: Amine functionalised surface. The first choice for covalent immobilisation of biomolecules. Couple to amine groups on the AnaChip™ surface via -NH2, -CHO or -SH groups on target biomolecule, with or without linker chemistry. Amine surface also carries positive charge, allowing the immobilisation of negatively charged biomolecules by physisorption.

Use: Suitable for study of polymers, surfactants, proteins, nucleic acids, carbohydrates, and lipids

Ordering information: Part No. 2007-111c (pack of 5)

Surface: Thiol functionalised surface for covalent immobilisation of biomolecules. Couple to thiol groups on the AnaChip™ surface via -NH2 or -SH groups on target biomolecule, with or without linker chemistry. Thiol surface also suitable for the physisorption of more hydrophobic molecules.

Use: Suitable for study of nucleic acids, polymers and proteins

Ordering information: Part No. 2007-113c (pack of 5)

Surface: C18 hydrocarbon functionalised surface for adsorption of hydrophobic biomolecules, usually those associated with membrane environments. Can also be used for the adsorption of lipids to form hemilayers as membrane mimics.

Use: Suitable for adsorption of hydrophobic polymers, proteins and peptides and forming lipid-based membrane mimics

Ordering information: Part No. 2007-112c (pack of 5)
