Dendrimer Interactions with Cell Membrane and Pore Forming Toxins
Dendrimers are hyper-branched polymeric nanoparticles with a central core molecule connected by successive dendritic branching layers. The structure controlled parameters of den-drimers such as size, shape, surface chemistry, ... -
Detection of charge-neutral modes to spin-wave excitations in graphene quantum Hall, and periodic magnetic field effect on Dirac electrons
In the quantum Hall (QH) regime, the electrical transport happens along the downstream chiral edge modes (dictated by the external magnetic field) while the bulk remains a vanilla insulator. However, it has been theoretically ... -
Deterministic Two Stage Clonal Expansion Model of Breast Cancer Epidemiology and its Utility for Optimal Screening Policies in India
Breast cancer (BC) has emerged as public health issue in India in last two decades sur-passing cervix cancer. Mortality from breast cancer is 30-40% higher than maternal causes. Breast cancer 5 year survival rates are ... -
