Tunability in Graphene Based Metamaterial Absorber Structures in Mid-Infrared Region

Autor: Shashank Kumar Gupta, Palash Kumar Basu

Publikováno v: IEEE Photonics Journal, Vol 14, Iss 3, Pp 1-5 (2022)

Tunable conductivity of graphene, makes it a promising material for metamaterials. There are various graphene tunable metamaterial absorbers in the mid-infrared region, whose absorption spectrum can be dynamically tuned by varying the Fermi potential

Isolation of Exosomes from Human Serum Using Gold-Nanoparticle-Coated Silicon Surface

Autor: Krishna Thej Pammi Guru, Nusrat Praween, Palash Kumar Basu

Publikováno v: Nanomaterials, Vol 13, Iss 3, p 387 (2023)

Exosomes, whose mean diameter ranges from 20 nm to 200 nm, are cell-secreted vesicles and are abundant in most biological fluids, such as blood, urine, tears, sweat, breast milk, etc. Exosomal size variations and their composition can be attributed t

Novel Gold Nanoparticle-Based Quick Small-Exosome Isolation Technique from Serum Sample at a Low Centrifugal Force

Autor: Krishna Thej Pammi Guru, Jamuna Surendran Sreeja, Dhrishya Dharmapal, Suparna Sengupta, Palash Kumar Basu

Publikováno v: Nanomaterials, Vol 12, Iss 10, p 1660 (2022)

Exosomes are cell-secreted vesicles secreted by a majority of cells and, hence, populating most of the biological fluids, namely blood, tears, sweat, swab, urine, breast milk, etc. They vary vastly in size and density and are influenced by age, gende
