NaBiF: Er, Yb upconversion particle as a multi-functional bio-marker
Atanu Ghosh, Krishna Kumari Swain, Agniva Das +6
The paper presents bismuth‑doped NaBiF4:Er³⁺,Yb³⁺ upconversion particles that show markedly higher quantum yield and controllable photoluminescence using two infrared lasers, enabl…
In-vivo femtonewton-sensing nanotribology of Tradescantia zebrina leaf cell inner surface using roll rotation detection
Snigdhadev Chakraborty, Mukul Sagar, Atanu Ghosh +5
Accessing the properties of a plant cell interior non-invasively is difficult due to the presence of a cell wall. Nanoparticles larger than 5 nm cannot be readily phagocytosed insi…
Intracellular phagosome shell is rigid enough to transfer outside torque to the inner spherical particle
Srestha Roy, Arvin Gopal Subramaniam, Snigdhadev Chakraborty +6
Intracellular phagosomes have a lipid bilayer encapsulated fluidic shell outside the particle, on the outer side of which, molecular motors are attached. An optically trapped spher…
A label-free sub-diffractive technique for 3D intracellular tomography using thermally induced convection currents
Jayesh Goswami, Shataneek Banerjee, Snigdhadev Chakraborty +8
Conventionally, 3-dimensional cellular tomography can be done with light sheet or multi-angle observations. Recently, a new technique was introduced where the cell was rotated usin…
