Magnetic nanorobots

In 2009, he along with Peer Fischer demonstrated the use of glancing-angle deposition to fabricate magnetic helical nanorobots. His group worked out the theoretical formulae to describe the dynamics of such nanorobots and presented techniques for their independent control.

In recent years his group has managed to demonstrate various applications of helical nanorobots including techniques to move in important biological environments, such as blood. and as probes for sensing the environment inside living cells.

His group is also developing magnetic nanorobots for targeted cancer therapy. Such treatments would be less invasive, with fewer side effects, and would be lower in cost as well.

Plasmonics and Metamaterials

Ambarish Ghosh and his group demonstrated a wafer scale technology to fabricate porous 3D plasmonic metamaterials which can be used over a wide range of wavelengths, including the visible. These metal-dielectric nanostructured films can be made in various geometries and configurations. Very recently, they have demonstrated a novel technique to integrate plasmonic nanoparticles with graphene in a sandwich configuration, allowing them to achieve unprecedented electromagnetic field enhancement and photodetection sensitivity. In 2019, his group showed the application of metal-dielectric hybrid nanorods in active opto-fluidic manipulation of sub-micron colloids.

Electron bubbles in Liquid Helium

The group led by Ambarish Ghosh demonstrated trapping of multielectron bubbles in liquid helium-4, which can open up new avenues in the study of two-dimensional electron systems at high densities, and on curved surfaces. The same group also performed high speed imaging of the "explosion" of an electron bubbles triggered by focused ultrasound.
