Summary

Automatically generated

O protocolo aqui descrito visa medir o diâmetro hidrodinâmico das nanopartículas esféricas, mais especificamente nanopartículas de ouro, em meio aquoso por meio da Análise de Rastreamento de Nanopartículas (NTA). Este último envolve rastrear o movimento das partículas devido ao movimento browniano e implementar a equação de Stokes-Einstein para obter o diâmetro hidrodinâmico.
