Professor Kattesh Katti's research has shown that green tea and gold nanoparticles can be used to treat prostate cancer. Katti, who was born in India and now works in the US, has won several awards for his work developing radioactive gold nanoparticles that can target and destroy cancerous tumors. His research also shows that gold nanoparticles can be produced through non-toxic, "green" methods using chemicals extracted from plants. While many Indian scientists leave for greater opportunities abroad, Katti credits his modest upbringing in India for allowing him to succeed through focus and hard work.

Green tea and gold can help treat prostate
cancer. Sounds incredible? Meet Professor
Kattesh Katti, whose research claims to prove
that.“Not every day is a great day in research.
But I'm hoping that one day, I'll be able to
develop nanoparticles that work when
injected only around the tumour to minimise
toxicity,” said Katti, who is visiting to Indian
Institute of Science-Bangalore.

In the past two weeks, India-born Katti has
won two major recognitions – the Hevesy
Medal Award 2015, which honours
outstanding achievement in radioanalytical
and nuclear chemistry, and the elite
fellowship of the National Academy of
Inventors. Katti’s research was instrumental
in the discovery of radioactive nanoparticles
of gold that can be used to target cancerous
cells and destroy tumours.

Nanoparticles can be produced in different
ways. “When toxic chemicals interact with
gold, they produce gold nanoparticles,” said
Katti. But he discovered that the same effect
can be achieved by using a “green” process.
Chemicals extracted from natural substances
like cinnamon, mango skin or soybeans have
similar powers. “Since nanoparticles are
being injected to the body, it’s better to
reduce toxicity of the chemicals used to
produce them,” said Katti.

With many awards and citations to his
credit, Katti is a top scientist today. But he
traces his roots back to a small town in
Karnataka and modest beginnings.
“There were times when we had to choose
between dinner and lunch. But that's the
beauty of the system in India. If you intend
to succeed it allows you to do that,“ said
Katti who lives in the US with his wife, a
senior research scientist at the radiology
department in the Missouri University , and
two children.

Born in Dharwad in a joint family of 30
members, Katti went to a nearby school
and picked up an interest in science
early on. He was hoping to become a
teacher, but a stint at the Indian Institute
of Science here changed the course of
his life.
“I was trained to be a teacher but going
to IISc changed the whole pathway ,“
said the 58-year-old, who completed his
PhD from Indian Institute of Science in
1984.

Many scientists like Katti have left to the
US, mostly because of the bigger
opportunities abroad. According to
“Global mobility: Science on the move,“
published by the Nature in 2012, India
sends the largest number of scientists
abroad and the US is the top destination
for foreign scientists.
“India needs to spend more money on
science and technology ,“ said Katti, who
also advocates for higher contribution
from the private sector to science.
