Design of fullerene-based biomarker for detection of lead impurities
Milanpreet Kaur,Ravinder Singh Sawhney,Derick Engles,Rupan Preet Kaur 한국통신학회 2016 ICT Express Vol.2 No.4
The fullerene-based molecular junction in a device configured for sensor applications in medical diagnostics has been evaluated in this study. The presence of highly carcinogenic agents such as lead is detected using this molecular device, which is configured and investigated using extended Hückel theory (EHT) and the non-equilibrium Green’s function. The electrical parameters that we calculated can be employed to determine the concentration of lead impurities by evaluating its transmission coefficients and molecular orbitals. Our results suggests that the alignment of current increases with increasing impurity level (i.e., of 6, 12, and 18 lead atoms), thus indicating sensor characteristics.
Non-invasive cancer detection using molecular device based on aromatic molecules

Major advances in the molecular diagnostics of screening tissue and blood samples have fueled the search for biomarkers and diagnostic nanosensors that can detect abnormalities early in their development cycles. In this paper, we propose an aromatic molecular junction-based biomarker that can trace the concentration of lead in any live sample. A nanomolecular device based on an anthracenedithiol molecule was modeled. Its electrical transport attributes were computed using a semi-empirical extended Huckel theory combined with non-equilibrium Green’s function formalism. We observed that the current and conductance assay had prominent changes when the molecular junction device was exposed to variant concentrations of lead. Based on our results, we propose aromatic molecular junction-based biomarkers that can detect even minor adulterations of lead when plied at operating voltage range.
