===Magnetic nanorobots===
In 2009 he along with [[Peer Fischer]] demonstrated the use of glancing-angle deposition to fabricate magnetic helical nanorobots.<ref>{{cite journal |last1=Ghosh |first1=Ambarish |last2=Fischer |first2=Peer |title=Controlled Propulsion of Artificial Magnetic Nanostructured Propellers |journal=Nano Letters |date=10 June 2009 |volume=9 |issue=6 |pages=2243–2245 |doi=10.1021/nl900186w |pmid=19413293 |bibcode=2009NanoL...9.2243G }}</ref> His group worked out the theoretical formulae to describe the dynamics of such nanorobots<ref>{{cite journal |last1=Ghosh |first1=Arijit |last2=Mandal |first2=Pranay |last3=Karmakar |first3=Suman |last4=Ghosh |first4=Ambarish |title=Analytical theory and stability analysis of an elongated nanoscale object under external torque |journal=Physical Chemistry Chemical Physics |date=2013 |volume=15 |issue=26 |pages=10817 |doi=10.1039/c3cp50701g |pmid=23694848 |bibcode=2013PCCP...1510817G }}</ref> and presented techniques for their independent control.<ref>{{cite journal |last1=Mandal |first1=Pranay |last2=Chopra |first2=Vaishali |last3=Ghosh |first3=Ambarish |title=Independent Positioning of Magnetic Nanomotors |journal=ACS Nano |date=17 April 2015 |volume=9 |issue=5 |pages=4717–4725 |doi=10.1021/acsnano.5b01518 |pmid=25824608 }}</ref>

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]].<ref>{{cite journal |last1=Ghosh |first1=Souvik |last2=Ghosh |first2=Ambarish |title=Mobile nanotweezers for active colloidal manipulation |journal=Science Robotics |date=10 January 2018 |volume=3 |issue=14 |pages=eaaq0076 |doi=10.1126/scirobotics.aaq0076 |doi-access=free }}</ref> and as probes for sensing<ref name="Sensing">{{Cite web |url=https://www.youtube.com/watch?v=yBifxe57_74|title=Nanorobots as Mobile Viscometers}}</ref> the environment inside living cells.<ref>{{cite journal |last1=Pal |first1=Malay |last2=Somalwar |first2=Neha |last3=Singh |first3=Anumeha |last4=Bhat |first4=Ramray |last5=Eswarappa |first5=Sandeep M. |last6=Saini |first6=Deepak K. |last7=Ghosh |first7=Ambarish |title=Maneuverability of Magnetic Nanomotors Inside Living Cells |journal=Advanced Materials |date=May 2018 |volume=30 |issue=22 |pages=1800429 |doi=10.1002/adma.201800429 |pmid=29635828 }}</ref><ref>{{cite journal |last1=Ghosh |first1=Arijit |last2=Dasgupta |first2=Debayan |last3=Pal |first3=Malay |last4=Morozov |first4=Konstantin I. |last5=Leshansky |first5=Alexander M. |last6=Ghosh |first6=Ambarish |title=Helical Nanomachines as Mobile Viscometers |journal=Advanced Functional Materials |date=June 2018 |volume=28 |issue=25 |pages=1705687 |doi=10.1002/adfm.201705687 }}</ref>

===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<ref>{{cite journal |last1=Johnson Singh |first1=Haobijam |last2=Ghosh |first2=Ambarish |title=Porous Three Dimensional Arrays of Plasmonic Nanoparticles |journal=The Journal of Physical Chemistry C |date=4 September 2012 |volume=116 |issue=36 |pages=19467–19471 |doi=10.1021/jp3062702 }}</ref><ref>{{cite journal |last1=Singh |first1=Johnson Haobijam |last2=Nair |first2=Greshma |last3=Ghosh |first3=Arijit |last4=Ghosh |first4=Ambarish |title=Wafer scale fabrication of porous three-dimensional plasmonic metamaterials for the visible region: chiral and beyond |journal=Nanoscale |date=2013 |volume=5 |issue=16 |pages=7224 |doi=10.1039/C3NR02666C |bibcode=2013Nanos...5.7224S }}</ref><ref>{{cite journal |last1=Singh |first1=Haobijam Johnson |last2=Ghosh |first2=Ambarish |title=Harnessing magnetic dipole resonance in novel dielectric nanomaterials |journal=Nanoscale |date=2018 |volume=10 |issue=34 |pages=16102–16106 |doi=10.1039/C8NR04666B }}</ref> 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.<ref>{{cite journal |last1=Paria |first1=Debadrita |last2=Roy |first2=Kallol |last3=Singh |first3=Haobijam Johnson |last4=Kumar |first4=Shishir |last5=Raghavan |first5=Srinivasan |last6=Ghosh |first6=Arindam |last7=Ghosh |first7=Ambarish |title=Ultrahigh Field Enhancement and Photoresponse in Atomically Separated Arrays of Plasmonic Dimers |journal=Advanced Materials |date=March 2015 |volume=27 |issue=10 |pages=1751–1758 |doi=10.1002/adma.201404312 }}</ref> 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<ref>{{cite journal |last1=Vadakkumbatt |first1=Vaisakh |last2=Joseph |first2=Emil |last3=Pal |first3=Anustuv |last4=Ghosh |first4=Ambarish |title=Studying electrons on curved surfaces by trapping and manipulating multielectron bubbles in liquid helium |journal=Nature Communications |date=1 August 2014 |volume=5 |issue=1 |pages=4571 |doi=10.1038/ncomms5571 |pmid=25081283 |bibcode=2014NatCo...5.4571V |doi-access=free }}</ref> 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<ref name="EB">{{Cite web |url=https://www.youtube.com/watch?v=bjDl23xBdyE|title=Electron Bubble Explosion in Liquid Helium}}</ref> of the "explosion" of an electron bubbles triggered by focused ultrasound.

== Awards and honors ==
Ambarish received the Young Career Award in Nano Science and Technology for 2017 from DST Nanomission, India. The [[Council of Scientific and Industrial Research]], the apex agency of the Government of India for scientific research, awarded him the [[Shanti Swarup Bhatnagar Prize for Science and Technology]] for his contributions to physical sciences in 2018.<ref name="Bhatnagar">{{Cite web |url=http://ssbprize.gov.in/WriteReadData/LatestUpdates/201809260331397455401SSBPrize2018.pdf |title=Shanti Swarup Bhatnagar Prize (SSB) for Science and Technology 2018|date=26 September 2018 |publisher=Shanti Swarup Bhatnagar Prize |access-date=2018-09-26}}</ref> He received the Prof. Ramakrishna Rao Chair Professorship<ref name="RRC">{{Cite web |url=https://www.iisc.ac.in/about/endowed-chairs/endowed-chairs-for-the-faculty/ |title= Ramakrishna Rao Chair Professorship|publisher=Indian Institute of Science |access-date=2019-11-03}}</ref> from 2017–2020.
