Avenida Mestre José Veiga, in Braga
 
The International Iberian Nanotechnology Laboratory (INL) is a Spanish-Portuguese research center in Braga, Avenida Mestre José Veiga, city of Braga, northern Portugal.

This institute is located next to the Gualtar Campus of the University of Minho, on a five-hectare municipal plot where the Bracalândia amusement park was located.

This structure is dedicated to research in the area of ​​nanotechnology and will have several workshops, laboratories, a library and auditoriums.

At the XXI Portuguese-Spanish Summit that took place in Évora on the 18th and 19th of November 2005, it was decided to create a Portugal-Spain R&D Institute, as a pioneering initiative for a new type of international institutional partnership in science and technology in Europe.

It was decided that the institute would be located in Braga-Portugal, would have as its first director a Spanish researcher (Professor José Rivas from the University of Santiago de Compostela, appointed at the time by the President of the Government of Spain) and should have around 200 researchers from Spain, Portugal and other countries, with an annual operating budget of around 30 million euros and an additional investment of the same value, provided in equal parts by the two countries.

The Iberian Institute of Nanotechnology has 14 thousand meters of laboratory area, in a building of around 20 thousand square meters, the first stone of which was laid at the XXIII Iberian Summit, which took place on the 18th and 19th of January 2008 in Braga.

It will also soon be equipped with a live science center so that the population can be shown the work that will be carried out there.

In 2007, the execution project was drawn up and a public tender for the work was launched. In 2008, the construction of the various buildings began, and in the following years equipment was purchased and specialists were recruited.

The inauguration of the first phase took place on July 17, 2009, and was attended by the President of the Republic, Cavaco Silva, King Juan Carlos of Spain, the Prime Ministers, José Sócrates and José Luiz Zapatero and the Science Ministers of both countries.

In the first phase, the University of Minho provided space in the Convento dos Congregados, for the development of the work of the installation committee.

As this project is intended to be open to private participation who wish to invest in concrete research for industrial application, Braga City Council will simultaneously create a Technological Park of Excellence nearby, integrated into the Tech Valley project, for the installation of technology-based companies.

In 2013, Portugal and Spain have budgeted a transfer of five million euros each to INL.

The value is below the 30 million euros of annual investment planned when the laboratory was launched by the previous governments of the two Iberian countries. In 2012, 80 employees of 19 nationalities worked at INL, but it was designed to have 400 workers working.

In 2017, around 230 researchers of around 30 nationalities worked at INL.

INL is dedicated to various applications of nanotechnology, including nanomedicine, food and environmental quality control, energy, photonics, nanoelectronics and nanosystems.
