Fabricating Large Scale Biomolecular Nanoarrays
12 Dec 2012Dip Pen Nanolithography® (DPN®) is an established method of nanofabrication in which materials are deposited onto a surface using a sharp tip. In this application note from NanoInk DPN was used to fabricate arrays of nanometer-scale features that served as attachment points for thiolated biomolecules. These binding sites were fabricated using a block co-polymer to transport small amounts of gold ions to defined locations on to a substrate. The printed droplets were heat treated to form gold nanoclusters at each deposition location, and were subsequently capable of tethering both protein and DNA molecules.

Genome AnalysisGenomics, the study of genomes, includes functional genomics, evolutionary genomics and comparative genomics. There are many genomic technologies such as DNA sequencing of whole genomes, computational biology and bioinformatics. DNA and nucleic acids must be isolated and concentrated from cells for analysis with kits, automated analyzers and software. Other useful technologies for studying genomics include PCR, microarrays and electrophoresis.ProteomicsProteomics is the systemic bioinformatics study of proteins and amino acids, including their structure, size, function and identification. Tools used in proteomics include chromatography, blotting and gels, protein arrays, mass spectrometry and ELISA and associated analysis software. Analyzers and proteomic systems should be sensitive, high resolution, fast and may be automated for high-throughput.Cell Lines Stem Cells and Primary CellsPrimary cell cultures, established cell lines and stem cells are vital for <i>in vitro</i> and <i>ex vivo</i> experimentation. High-quality cells, optimized for your applications, alongside optimized cell substrates, growth medium and supplements, are critical for experimental success. Explore a range of cells suitable for your applications, including isogenic cell lines, competent cells, induced pluripotent stem cell (iPSC)-derived cell lines, fungal/bacterial/mammalian cell lines, stem cells and cancer cell lines.
