Imperial spinout will scale its activity to help create a new generation of sustainable, high-performance textiles using an entirely new class of fibres.
Solena Materials has raised $6.7 million (£5.1 million) in seed funding, following a $4.1 million (£3.1 million) pre-seed funding round in 2022, that it will use to produce protein fibres at scale.
Imperial spinout Solena Materials has raised $6.7 million to scale up production of sustainable, biodegradable protein fibres designed using AI and engineered microbes. These novel fibres, offering high performance and lower environmental impact, could transform fashion and technical textiles. The investment will fund expansion and support partnerships with leading fashion brands.
The company uses AI techniques to custom-design fibres at the molecular level which are then produced using engineered microbes. Its AI techniques allow it to optimise performance characteristics of the fibres such as appearance, hand-feel and tensile strength, and could result in new and higher performing fashion, sports apparel, and technical textiles.
Solena's co-founder and CEO, Dr James MacDonald , developed the techniques behind the company as a researcher at Imperial in collaboration with his other co-founders. 'We're creating protein sequences that don't exist in nature to have the performance specifications we need while also being highly manufacturable,' he explained.
Professor Paul Freemont, Solena co-founder and Head of the Section of Structural and Synthetic Biology in Imperial's Department of Infectious Disease , said: 'This extraordinary technology is opening up a whole new paradigm in the design of protein fibres. James has created new protein molecules that can form fibres that currently don't exist. That's really exciting because no one has been able to do that before – we've always had to rely on what nature gave us. Now we're building our own protein fibres from first principles. This will be a paradigm shift.'
Because the microbes used to produce the fibres use renewable feedstocks, the company's fibres could also potentially be produced at a lower environmental cost than synthetic textiles made from petroleum and resource-intensive natural fibres. The fibres are also biodegradable, unlike traditional synthetic fibres such as polyester.
Solena launched in 2022 with premises in Imperial's White City Incubator and pre-seed investment from Insempra. It has now raised further funds in a round led by Sir David Harding, alongside SynBioVen and Insempra.
It will use the investment to move from premises in the I-HUB building on Imperial's White City Deep Tech Campus to a larger facility, with an ambition to stay close to Imperial. This will allow the company to scale production of its novel textile fibres in partnership with well-known fashion brands.
Professor Milo Shaffer, Solena co-founder and Chair in Materials Chemistry at Imperial , said: 'Solena is particularly exciting, not only as a new class of high performance sustainable fibres for a wide range of applications, but also as an example of a paradigm shift in accelerating materials discovery. The combination of computational design with rapid evaluation in fibre form, directly feeds to scaled up production and implementation, exploiting established textile technology.'
Dr MacDonald shared details of the investment at the SynBioBeta conference in California, near Imperial Global USA, a hub that is helping the university build links with partners such as businesses and investors in the US.
