Home > Press > Argonne chemist wins AWIS Innovator Award for nanoparticle research

Abstract:
The Chicago chapter of the Association for Women in Science (AWIS) granted its third annual Innovator Award to Tijana Rajh, group leader of the Nanobio Interfaces research group at Argonne National Laboratory's Centre for Nanoscale Materials. The award honours contributions to science in the Chicagoland area. Rajh received the award for her work studying semiconductor nanoparticles, a field with applications from solar power to cancer research.

Argonne chemist wins AWIS Innovator Award for nanoparticle research

Argonne, IL | Posted on July 21st, 2009

Rajh cites Marion Thurnauer, a longtime Argonne scientist and former director of the Chemistry Division, as her mentor. 'At the time she was hired at Argonne, and for the next eight years, she was the only female Ph.D. staff member of Argonne's Chemistry Division,' Rajh said. 'That experience prompted her to encourage broader searches for women to be represented in the Argonne job candidate pool.'

Rajh herself grew up in Yugoslavia, where, she says, it was more common for women to have careers in science. A friend of her mother's brought Rajh to visit her workplace, a scientific institution much like Argonne. 'I fell in love with it,' Rajh said. 'There was absolutely no question what I was going to do with my life. And then when I came here,' she added, smiling, 'I was hooked.'

While finishing her undergraduate physical chemistry degree at the University of Belgrade, a professor invited her to join a research project attempting to split water into hydrogen and oxygen molecules for fuel purposes. She didn't know it, but it was the jumping-off point for a long career studying semiconductor nanoparticles - tiny particles made from materials which form the heart of modern electronics. Their photoactivity and stability is exactly what makes them good for many uses, from pollutant cleanup to medical imaging.

Rajh and the research team noticed that the particles of the same chemical composition appeared in different colours as researchers shrunk them smaller and smaller. Nanoparticles can change colour, and other characteristics, with size: a quirk useful for many applications. 'When you see it for the first time, it's so amazing,' Rajh said. Together with her advisor Olga Micic and collaborator Art Nozik at the National Renewable Energy Laboratory, she authored one of the first three papers ever written about colloidal quantum dots (1985).

Thurnauer recruited Rajh in 1994, where she began studying how to use nanoparticles in a variety of applications: to remove heavy metal pollutants from the environment, write data to nanocircuits in computers, and link nanoparticles with biological materials.

For example, Rajh works with particles made of the semiconductor titanium dioxide (TiO2), which is white. When combined with organic compounds such as vitamin C or dopamine, which are also white, nanoparticles turn a brilliant red - indicating that the two materials are interacting at the molecular level. This discovery allowed her and her team to electronically link TiO2 particles with DNA and other biological molecules, opening a whole new dimension of possibilities. One of the team members, Elena Rozhkova, is working to apply the particles to cancer treatment. 'She marks glioma cancer cells with TiO2 particles,' Rajh explained, 'and doctors could use light of a certain energy to destroy only those marked cells, leaving healthy brain cells intact.'

At the core, though, Rajh loves basic science the best. 'I love research, it's so cool,' she said. 'It's like a puzzle. There's a problem, and you look at it and start making connections, and very slowly the whole picture opens up.'

Rajh received her Ph.D. in 1986 from the University of Belgrade in Yugoslavia. Prior to working at CNM, she joined Argonne's Chemistry Division in 1996 and has been a prolific researcher, co-authoring six papers in 2008 alone.

She is the third scientist to be recognised by the Association for Women in Science Chicago Area Chapter, a nonprofit organisation dedicated to advancing women in the field of science. The group formed in 1971 and has since expanded nationwide. Chapters advocate for women in all scientific fields, publicise women's achievements, and hold educational workshops for students. The Innovator Award recognises achievements in science in the Chicagoland area.
