With the advent of carbon materials such as CNTs and graphene, nanotechnology is paving the way for new superior nanodiagnostic nanodevices. Carbon materials such as CNTs are well known to be bio-compatible and surprisingly more evidence shows them to be non-toxic. In addition, similar carbon materials are used daily in mechanical heart valves and have proven to be have excellent blood compatibility and physical properties. Also interesting is that carbon materials show antithrombotic properties with superior non-fouling attributes. Aneeve is exploiting these attributes in developing next-generation nanodiagnostic sensors using low cost printing techniques. Aneeve is currently developing various medical sensors printed on catheters and disposable plastic test strips for hormones, hormone disruptors and toxins.
