"Journal of Biosensors & Bioelectronics is one of the open access journals. The journal is the best in providing and approaching the current research in the related field. The Journal provides the best information by accepting original research, review, clinical case reports. Quantum nanosensors are based on intrinsic resonances of metallic nanoparticles and semiconductor quantum dots. In this report, we propose ultra-sensitive sensors based on fundamentally different concepts and principles. In these sensors the rules of quantum mechanics are used to detect ultra-small variations of the refractive index of the environment. These quantum nanosensors are based on hybrid systems consisting of metallic nanoparticles and quantum dots. Interaction of these systems with a laser field generates quantum coherence and coherent exciton-plasmon coupling. Group is an organization known for its contribution towards the scientific community. PrimeOA Publications has more than 700+ peer-reviewed journals which are publishing quality articles and conduct around 3000+ International Scientific Conferences worldwide. The Journals are supported by strong Editorial Members""Journal of Biosensors & Bioelectronics is one of the open access journals.
