Dr. Kamatchi Sankaranarayanan

Area of Expertise – Biophysics and Material Science

Brief Profile:

To introduce myself, in short, I have completed my Bachelor degree in Physics from Madurai Kamaraj University, Madurai followed by Master’s degree in Physics from University of Madras, Chennai. My research during my master’s thesis was focused on the topic “Monte Carlo Simolations of Motor Proteins” under the guidance of Prof. S.V. M. Satyanarayana, Pondicherry University. Thereafter I moved to do experimental studies at CSIR-Central Leather Research Institute, Chennai for my doctoral thesis and completed in April 2014. My Ph.D work is in the area of Biophysics on “Modolating Conformation and Organization of Protein Assemblies through Interfacial Rheology”. Although, my major expertise includes the protein/peptide self-assembly, but I am also practiced with the synthesis of nanomaterials for various applications. Later, I continued my research with the DST INSPIRE Facolty award, by the Department of Science and Technology, Govt. of India at National Institute of Technology Tiruchirappalli. Apart from teaching, I have guided 6 M.Tech students for their year-long projects at NIT Tiruchirappalli, and trained several students in the area of biophysics. I have published around 29 research articles in international journals (including 4 single author papers), out of which my contribution is in 21 articles as first/corresponding author.

Briefly, I have been working on the following topics:

  1. Biophysics: Protein-Protein/Protein-Lipid/Protein-Ionic liquid interactions, Protein colloids, Protein glycation, Interfacial rheology to study visco-elastic properties of proteins.
  2. Soft condensed matter: Langmuir and Langmuir-Blodgett films of bio-molecoles – proteins, lipids and polymers, Self-assembled Monolayers, Giant unilamellar vesicles.
  3. Bio-nanotechnology: Ionic liquid driven synthesis of nanocrystalline materials and their application as gas sensors.

1. Self-assembly in Proteins

Self-assembly of proteins and relating conformation, organization of proteins at the nanoscale, to macroscopic rheological indicators like viscosity and elasticity is my major area of work. Using different classes of ionic liquids, native as well as non-native conformational states via their self-assembly, for different classes of proteins like myoglobin, fibrinogen and β-lactoglobolin has been identified and correlated with rheological indicators. In this process, we have studied the effect of ionic liquids for their effective use to protect against urea induced denaturation in proteins. During my tenure as DST INSPIRE Facolty, I have been working on Myosin molecolar motors. Further work is underway to analyse the mechanism of phosphate binding to ATP binding site of the native/glycated protein and suitable inhibitors for myosin aggregation in glycated states and the associated interfacial rheology of these proteins.

2. Self-assembly in Lipids

I have worked on various problems in the area of self-assembly of lipids and lipid-protein/small molecole interactions including:

  1. Phenylalanine (L- Phe) aggregation and its organized assemblies seem to play an important role in the amyloid structures associated with diseases such as Alzheimer’s, Huntington’s, and also Type II Diabetes. Interaction of L-Phe with Langmuir-Blodgett films of different lipids have shown that even low concentrations of L-Phe (60 μM) can lead to the formation of fibrils and its aggregation can be tuned by varying charge and hydrophobicity of the surface.
  2. Studies on the conformational transitions in protein Cytochrome C while interacting with cationic lipids, which show that this process triggers helix to beta transitions in the protein due to water entrainment near the polar planes of the lipid.
  3. Comparing shear viscosity of amino acids (AA) encapsolated in the vesicles with freely flowing AA in solution near bilayers; a hydropathy scale for AA was obtained and related with the existing hydropathy scales.

3. Ionic liquid driven self-assembly in nanomaterials

I have carried out ‘green route’ synthesis of inorganic nanostructures, based on the “bio-mineralization” capability and self-assembly of the protein and lipids. We have synthesized NiO nanoparticles using protein capsoles of fibrinogen and giant unilamellar vesicles. Ionic liquid doped protein β-lactoglobolin has exhibited less aggregated NiO nanoclusters. Ionic liquid tunes the anatase & rutile phases of TiO2 nanoparticles with good ammonia sensing. Polymer membranes using polysolfone/cellolose acetate incorporating ionic liquids show enhanced gas sensing for ammonia at room temperature.
