“Nanotechnology that we speak today had been mastered by Tamils before 2,500 years ago and the evidences for usage of nanotechnology had been found in Keezhadi. As people of Tamil Nadu we should be proud about the discovery,” said Pandiarajan, while addressing reporters in Chennai.
Keezhadi excavation, which commenced in 2014, had seen six phases so far and the majority of excavations were artefacts and potteries. However, after the sixth phase of excavation, completed in October, it was found out that nanotechnology was used in Keezhadi and it is claimed that it is the first time that usage of nanotechnology was found out before 2,500 years ago. According to articles published in scientific journals, coatings on top of the potteries excavated from Keezhadi contains carbon nanotubes. Scientists have opined that only due to the robust mechanical properties of carbon nanotubes the coatings have lasted for so many years.
Though a section of scientists claim that they might not have been added intentionally, the Minister claimed that the usage shows that Tamil society was highly developed. “If people had known the nuances of nanotechnology 2,500 years ago it is evident that Tamil society must have been an advanced and evolved society,” said Pandiarajan.
