97 Break a sweat


Silicone is beloved by medical device designers for its biocompatibility, but there are reasons why people are not all coated in plastic. Even if it’s only applied to the skin, silicone’s impermeability prevents sweat from evaporating, causing discomfort and inflammation. Allie Anderson speaks to Ahyeon Koh and Matthew Brown of Binghamton University about a possible solution. Their electrospun PDMS, which behaves more like the collagen and elastic fibres of the epidermis than a plastic film, can be integrated with skin, as well as neural and cardiac tissue, with reduced inflammation at the application site.

When spider webs get inside, our first impulse is to clean them away. But the sticky filigree isn’t dirty in itself. In fact, the material we try to keep out of our houses might be the key to tackling bacterial infection in our bodies. Natalie Healey speaks to


it can help create devices that perform better inside the body. Atieh Moridi of Cornell University and Amit Bandyopadhyay of Washington State University tell Jim Banks how 3D printing is redefining biocompatibility.

Packaging 114 Outside the box


By paying closer attention to how patients and practitioners interact with packaging, researchers are finding answers to some long- standing medical conundrums, improving healthcare and catalysing new industry collaborations in the process. Radhika Holmström finds out more from lead members of the new Kilmer Innovations in Packaging group: Laura Bix, a professor in the school of packaging at Michigan State University, and Jiyon Lee, a packaging engineer at Amgen.

118 A total meltdown The Covid-19 pandemic has highlighted the pharma sector’s dependence on the cold chain for vaccine distribution. Hundreds of thousands of cold storage devices are being used to ship vaccines worldwide, while local ‘fridge farms’ have been rolled out to house deliveries. But is there another way? Lynette Eyb speaks to David Hipkiss, CEO of Enesi Pharma, and looks at the development of delivery technologies that may one day help reduce vaccine waste and refine – even revolutionise – cold storage in a rapidly warming world.
