Please keep the product serial number you receive with your sample, as it will assist us if you have inquiries about the product. The serial number (S/N) is located on the clear vacuum-sealed bag your graphene sample arrived in and your invoice. We have taken the guesswork out of your project by analyzing every piece of graphene that leaves the door. Take advantage of the data files available for your graphene batch. Contact us if you require additional characterization of your graphene.

Silver nanowire (AgNW) ink is the leading solution for transparent conductive electrodes (TCEs) that require both high conductivity and optical transparency. At loadings that achieve sheet resistance below 10 Ohm/sq, AgNW films maintain optical transmittance above 85% — performance that rivals ITO at a fraction of the cost and with far superior flexibility. Unlike ITO, silver nanowire electrodes do not crack under bending, making them essential for rollable displays and conformable biosensors. Cheap Tubes synthesizes 30 nm outer diameter silver nanowires in-house at our Vermont facility, giving us direct quality control over aspect ratio, concentration, and lot-to-lot consistency — shipped at 25 mg/mL in isopropanol (IPA). Cheap Tubes supplies silver nanowire ink for transparent electrode applications in touch screens, OPV, and flexible electronics. Both ink types are formulated for compatibility with screen printing, gravure, flexographic, and inkjet deposition methods. Silver nanowire ink is the choice when optical transparency is required alongside low sheet resistance.

Amine | -NH₂ | Basic, highly water-dispersible; reacts with COOH, epoxides, aldehydes | Drug delivery, biosensors, crosslinked epoxy composites Amine (-NH2) groups are introduced via diamine coupling to -COOH and provide direct bonding to epoxy resins and conjugation chemistry to biomolecules via standard NHS/EDC coupling. -COOH and -NH2 functionalized MWCNTs are the standard substrates for biomolecule conjugation... use glutaraldehyde or NHS-PEG-NHS linkers between -NH2 surfaces and amine-bearing biomolecules. For dispersion in aqueous biological or analytical applications, -COOH and -NH₂ groups provide colloidal stability through electrostatic repulsion (high negative or positive zeta potential) without requiring surfactants that would need to be removed in downstream processing. This makes functionalized CNTs the preferred choice for drug delivery systems, biosensors, and diagnostic conjugation chemistry.
