Nanomaterials and Bio-Nano Interfaces

 

Group Leader: Dr. Vivek Pachauri

Vivek Pachauri studied Chemistry and Biological sciences (2000-2005) in Dr. Bhim Rao Ambedkar University Agra, in India. He recieved 2005 student research fellowship from the prestigious Jawaharlal Nehru Center for Advanced Scientific Research (JNCASR), Bangalore in the field of Chemistry. He began his formal research career at the Govt. of India, Department of Science and Technology Unit on Nanoscience and Nanotechnology (UNANST-DST) situated in Indian Institute of Technology Madras (IIT Madras). In 2006, he joined Department of Chemistry, Indian Institute of Technology Delhi (IIT Delhi), on a research fellowship and worked on sol-gel chemistry routes for synthesis of chalcogens. Thereafter, in 2007, he moved to Germany for his doctoral work and joined the Department of Nanoscale Science at the Max Planck Institute for Solid State Research (MPI-FKF) Stuttgart in the guidance of Prof. Klaus Kern.

Starting his research career with a focus on chemical routes for self-assembly of nanomaterials, Dr. Pachauri has continued on integration of chemistry-based approaches for large-scale system-integration and development of bioanalytical platforms. His doctoral work produced a new class of one-dimensional (1D) ion-sensitive field-effect transistors (ISFETs) based on semiconductor nanowires (sNWs), fabricated site-selectively on a chip, using solution-based self-assembly growth. In 2011, he recieved his doctoral degree in Physics from Ecole Polytechnique Federale de Lausanne (EPFL), Switzerland. Dr. Pachauri continued at the MPI-FKF as a postdoctoral researcher working on new nanoscale device concepts for applications such as liquid-sensing and optical sensing based on 1D and two-dimensional (2D) semiconductors.

In 2012, Dr. Pachauri joined Biomedical Signalling Group at University of Applied Sciences Kaiserslautern and started activities towards bottom-up system-integration of graphene based materials (GBMs) as well as silicon based nanofabircation of ISFETs for biosensor applications. Dr. Pachauri started his research activities at IWE1 in the beginning of year 2018 as a new research group focused on Nanomaterials and BioNanoInterfaces.

Main interests of the research group are new materials integration, evolution of NanoBioInterfaces for advanced sensorics, and role of such integrated materials and interfaces in postCMOS technologies. He has published more than 25 peer-reviewed articles in international journals.

Current topics:

  • System integration of graphene-based and other two-dimensional materials,
  • New materials and interfaces e.g. van der Waals, for sensor applications,
  • Informatics of BioNanoInterfaces,
  • Biomolecular programming tools,
  • Evolution of Bio-Nano interfaces.
