Michelle Emma Dickinson MNZM, also known as Nanogirl, is a nanotechnologist and science educator based in New Zealand.

[8] Initially Dickinson used the name "Nanogirl" to write a science blog, then as it became more popular she started a YouTube channel and began to speak at schools and events.

While the company generated revenue through various educational services and products, it also received external public funding to support its initiatives.

The company went into liquidation in 2024 because of financial challenges due to cuts to government funding, sponsorship and the cost of living crisis.

[13] Dickinson co-founded the charity OMGTech in 2014 with Vaughan Rowsell and Rab Heath to provide children of all ages and backgrounds access to learning opportunities about technology.
