Two British inventors are amongst the 15 contenders in this year's European Inventor Awards. Joshua Silver, a professor of physics at University of Oxford, was nominated for inventing self-adjustable glasses and Leigh Canham, for his break-through discovery which uses  tiny silicon implants with nano-sized pores  to deliver medicinal and therapeutic agents directly into tumours.

With Professor Silver's invention wearers can adjust the glasses themselves and without the assistance of a healthcare professional. They simply look at a reading chart and adjust the correction until they can see the letters clearly.  These lenses have the potential to dramatically improve quality of life, especially in the developing world where there is a lack of eye care professionals. More than 30,000 pairs of Silver's glasses have already been sent around the world - reaching about 20 countries such as Ghana, Liberia, Bolivia, Cameroon, Pakistan, and Kosovo.

    According to figures published by the World Health Organization (WHO), uncorrected vision problems result in significant losses in productivity - about €88.2 billion (£103 bn) annually.

    Leigh Canham's pioneering research has led to the development of a new form of porous silicon, called BioSilicon.  The honeycomb structure and semiconductor properties of BioSilicon enable drugs and other therapeutics or vaccines to be released slowly over hours, days, months or even years.   At the end, all that is left in the body is pure silicon, which dissolves and is safely excreted via the kidneys.  Drug loaded BioSilicon can be taken orally, by injection, transdermally, via patch, implant or coatings.

    Canham's research has also led to the development of biodegradable micropiercers, microneedles and biolistic bullets, capable of delivering drugs directly into a selected organ or even a specific cell. This has important implications for many areas of medicine including new potential treatments for cancer and blinding eye disease.

    The two inventions were chosen from a larger number of proposals submitted to the European Patent Office and underwent rigorous examination before being selected by a high calibre international jury. 

    Prizes will be awarded for five categories – industry, research, small and medium-sized enterprises (SMEs), non-european countries and lifetime achievement.

    Europe's most prestigious innovation prize will be awarded on 19 May in Budapest, Hungary.


    The awards were launched by the European Patent Office (EPO) in 2006 with the support of the European Commission.   This year the EPO is being supported once again by the Commission, as well as the Hungarian Presidency of the Council of the European Union.
