What is a nanoparticle?
A nanoparticle is a particle between 1 nm1 \, \text{nm}1nm and 100 nm100 \, \text{nm}100nm in size. This is approximately 1×10−9 m1 \times 10^{-9} \, \text{m}1×10−9m to 1×10−7 m1 \times 10^{-7} \, \text{m}1×10−7m.
Step-by-step lessons covering AQA GCSE Chemistry 2.4.2 Uses of nanoparticles for Foundation and Higher tier. Each lesson works through exam-style questions in Paper 1 and Paper 2 format. Nail the core quantitative topics — moles, balancing equations and calculations — early on, since they underpin higher-tier questions across every paper and topic.
