Nanotechnologies: Where should they take us? Have your say

Nanoyou Lab Experiment C- Teacher Document (14-18)

EXPERIMENT C illustrates the principle of a colorimetric nanosensor. In this experiment students use a plasmonic colorimetric sensor made of nanoparticles: a gold colloid (containing gold nanoparticles) is the sensing material, and the addition of an analyte (such as salt or sugar) induces a change in the aggregation of the nanoparticles in the colloid, which is reflected in a change in its colour. Similar colloids are used in the development of moder biosensors. The experiment is designed for the 14-18 years age group. This is a teacher document to provide them with some background information as well as instructions for preparing the experiments. This experiment is one of four experiments contained in the NANOYOU Teachers Training Kit of nanoscience and nanotechnologies.


The NANOYOU project aimed to increase young people’s basic understanding on nanotechnologies (NT) and to engage in the dialogue about its ethical, legal and social aspects (ELSA) through a strong school program for students aged 11-18 and a wide range of activities in Science Centres for those aged 18-25

About nanopinion

  • nanopinion is an EC-funded project bringing together 17 partners from 11 countries with the aim of monitoring public opinion on what we hope from innovation with nanotechnologies. The project is aimed citizens with a special focus on hard-to-reach target groups, which are people who do not normally encounter and give their opinion nanotechnologies at first hand.
  • Dialogue is facilitated online and in outreach events in 30 countries presenting different participatory formats.
  • To promote an informed debate, we also run a strong press & social media campaign and offer a repository with more than 150 resources.
