CV

Prof. Yitzhak Mastai was born in 1966 in Tel Aviv Israel. He obtained his B.Sc in physical chemistry from Bar-Ilan University in 1989 and received his PhD from the Weizmann Institute of Science with Prof. Gary Hodes on nanomaterials synthesis (1999). He then went to the Max Planck institute of colloids and interfaces for 3 years, as postdoctoral fellow to work with Prof. M. Antonietti and Prof. H Cölfen on biomimetic chemistry and chiral polymers.

In 2003 joined the staff of the chemistry department at Bar-Ilan University, where he is currently a Professor at the institute of nanotechnology at Bar-Ilan University leading the nano chirality laboratory. Prof. Mastai’s earlier interests included nanomaterials synthesis and characterization. His current research is focused on the synthesis and analysis of chiral nanosurfaces, chiral self-assembled monolayers and polymeric chiral nanoparticles. Mastai has published more than 100 scientific articles and book chapters on various aspects of nanomaterials and chirality at the nanoscale. Among his previous awards were the Minerva fellowship for postdoctoral (2000) and the Yigal Alon fellowship (2003) for or outstanding young researchers award of the Israel academy for higher education.

Research Summary

My primary field of research is chirality at the nanoscale, with a focus on preparation and application of nano-chiral surfaces for enantioselective processes. My research interests can be divided into several areas:

Chiral surfaces based on self-assembled monolayers

This research concerns fundamental studies of chiral surfaces based on ultrathin molecular architectures, such as self-assembled monolayers (SAMs), on solid supports. We were pioneers in the study of chiral SAMs for the preparation of chiral nanosurfaces for chiral resolution by crystallization. In a series of papers, our research group has shown that chiral SAM surfaces can be employed as resolving auxiliaries in the crystallization of amino acids from solutions. Recently we presented an innovative new type of chiral surface based on a chiral SAM coated with ceramic nanolayers that preserves the enantioselectivity nature of the chiral SAM and enables its protection. These surfaces can lead to a new class of chiral nano-surfaces with the improved characteristics that are necessary for any chiral application.

 

 

Chiral polymeric nanoparticles

This research concerns the development of polymeric nanoparticles fabricated using emulsion (mini or micro) polymerization. For example, we developed chiral polymeric nano- and microspheres that can act as chiral auxiliaries and be utilized for enantioselective crystallization. We are also developing chiral polymeric nanoparticles of controlled size and shape for other chiral applications such as a chiral stationary phase for chromatographic separations and as catalytic systems for stereoselective reactions.

 

Chiral mesoporous silica

Our group is also involved in the development of chiral mesoporous silica by chiral imprinting or by cooperative self-assembly of chiral amphiphiles and silica precursors. Our research focuses on the fabrication of chiral mesoporous materials and exploring the mechanisms involved in their formation and their chiral recognition.

 

New chiral analytical techniques

The group is also working on the development of new analytical methods to probe chirality at the nano-scale. We pioneered the development of near-field scanning optical microscopy (NSOM) and isothermal titration calorimetry (ITC) for the determination of chirality at the nanoscale.

Chiral ionic liquids

The influence of long alkyl chains and chiral centers on the structure and properties of ionic liquids at interfaces are studied. Langmuir films of ionic liquids on liquid mercury are studied by tensiometry, surface specific X-ray methods and spectroscopy.  Further applications of chiral ionic liquids for chiral recognition and chiral separation are considered.

Atomic layer deposition of metal-oxides thin films onto chiral biological macromolecule

This project is designed to produce a new platform for stereoselective applications based on chiral metal-oxide thin films surfaces. The new chiral surfaces are based on biological macromolecules with a complicated spatial structure, used as a model system. The biological molecules are coated with nano-sized metal oxide layers by atomic layer deposition (ALD) process, for obtaining chiral metal oxide surfaces.

Chiral polymer nanoparticles synthesis and application for chiral separation

In our work we prepare chiral polymeric nanoparticles based on the polymerization of N-acryl amino acids monomers in miniemulsion systems (o/w). The chiral nature of those nanoparticles is proven by isothermal titration calorimetry (ITC) of chiral molecules.

Chiral silica colloidosomes, synthesis and applications

Colloidosomes have shown a high potential in a number of technological applications related to encapsulation techniques. The application of the colloidosomes strongly relies on facile and lowcost preparation methods allowing tunable characteristics such as wall thickness, rigidity and porosity. Our aim is to prepare chiral silica colloidosomes in Pickering emulsions and to explore their enantioselective ability in different chiral systems.

Antifreeze activity of surfaces based on self-assembly of antifreeze proteins

Antifreeze proteins (AFPs) are unique examples of natural antifreeze materials that have specific interactions with water and ice. AFPs, first found in the blood and tissues of Antarctic and some northern marine fishes, are essential to prevent the fish from freezing at low temperatures.
