    ABSTRACT: It is well known that there are three types of dimers belonging to the three different orientations in a honeycomb lattice, and in each type all dimers are mutually parallel. Based on a previous result, we can compute the partition function of the dimer problem of the plane (free boundary) honeycomb lattices with three different activities by using the number of its pure dimer coverings (perfect matchings). The explicit expression of the partition function and free energy per dimer for many types of plane honeycomb lattices with fixed shape of boundaries is obtained in this way (for a shape of plane honeycomb lattices, the procedure that the size goes to infinite, corresponds to a way that the honeycomb lattice goes to infinite). From these results, an interesting phenomena is observed. In the case of the regions of the plane honeycomb lattice has zero entropy per dimer—when its size goes to infinite—though in the thermodynamic limit, there is no freedom in placing a dimer at all, but if we distinguish three types of dimers with nonzero activities, then its free energy per dimer is nonzero. Furthermore, a sufficient condition for the plane honeycomb lattice with zero entropy per dimer (when the three activities are equal to 1) is obtained. Finally, the difference between the plane honeycomb lattices and the plane quadratic lattices is discussed and a related problem is proposed.

    ABSTRACT: There have been considerable advances in the field of nanotechnology-based biosensors and diagnostics (NBBD) during the last two decades. These include the production of nanomaterials (NMs), employing them for new biosensing and diagnostic applications, their extensive characterization for in vitro and in vivo applications, and toxicity analysis. All these developments have led to tremendous technology push and successful demonstrations of several promising NBBD. However, there has been a significant lag in their commercialization, especially due to the lack of international regulatory guidelines for evaluating the safety of NMs and the growing public concerns about their toxicity. Despite these numerous advances and the recent regulatory approval of several NMs, it still remains to be seen if NBBD are superior to conventional ones (not based on NMs), reliable, reproducible, cost effective, and robust enough to meet the requirements of industries and healthcare. This manuscript provides a critical review of NBBD, the technology push, and the industrial/healthcare requirements.
