Sampling of dermal Interstitial Fluid (dISF)

About us

With the tremendous breakthroughs achieved in analysis methods, the guidance received from number crunching apps and the awareness that comes from our connected modern lifestyle with a smart device always at arm’s reach; The missing link has been the very first part of the chain - How to get biomarkers out of the body using methods compatible with our modern way of life?  

Who we are

Founded on the premise of radically improving healthcare, the team set out to develop hollow microneedles that can sample dermal interstitial fluid in a pain-free and easy to use way.
After almost 10 years of development, the company is entering into numerous clinical trials with the aim of characterizing both the system and dISF itself.

How we work

Ascilion has developed a platform technology for sampling of dermal interstitial fluid. We collaborate with partners in all segments of life sciences on customized versions of the product tailored towards the application at hand. The core of all products is a chipset with a plurality of hollow microneedles and an application-optimized collection system for the sampled fluid.
Sampling of dISF has never been easier with on-screen monitoring, precise sub-pressure control and pre-defined sampling sequences.

How it began

Ascilion was founded in 2012 with a mission to solve the problem of sampling dermal interstitial fluid in a timely and pain-free way. A team of engineers with a thorough understanding of MEMS technology and microfluidics took on the challenge of solving what turned out to be a very complex problem.

”We are impressed by Ascilion’s technology platform and by the team behind the company. Ascilion’s products are at the forefront and can contribute to developing and improving today’s diagnostic methods. Nordstjernan’s ambition is to continue growing in the health sector, and medical technology and diagnostics are areas we actively want to invest in. We look forward to supporting Ascilion in the company’s future development,” says Nordstjernan’s CEO Peter Hofvenstam.

Ascilion appoints Simon Grant as Chief Executive Officer

STOCKHOLM, SWEDEN, October 3, 2023 / -- Ascilion AB ("Ascilion") the world leader in interstitial fluid (ISF) sampling for biomarker investigation announced yesterday that the Board has appointed Simon Grant as Chief Executive Officer (CEO).

Simon has extensive Life Science industry experience, having held management positions in smaller startups such as Neoventa and Synectics Medical, and large multinationals such as Medtronic and Sandvik. Most recently Simon held the position of CEO at SciBase AB, a Swedish point-of-care diagnostics company listed on Nasdaq First North, Stockholm.

Sten Dahlborg, Chairman of the Board at Ascilion commented: "We are very happy to welcome Simon as CEO, and his appointment signals a new phase in the development of Ascilion. Simon brings extensive commercialization experience, having developed and introduced more than a dozen new medical technologies in the international market. His enthusiasm towards our technology and its application reinforces our belief in its potential" Furthermore, he added: "I would also like to take the opportunity to thank Markus Renlund for the excellent work he has done to lead the company to this stage. Markus will continue with the Company, both as a Board member and in his role as Technology and Innovation Lead.

Simon Grant commented "In my opinion interstitial fluid sampling has the potential to disrupt the standard of care in multiple clinical specialties and drive significant research and wellness applications. ISF contains a ‘treasure trove’ of biomarker information that until now has been mostly untapped because it is practically so difficult to extract. Ascilion is a world leader in hollow microneedles, and it is that technology that enables us to access ISF in useful volumes for the very first time. I believe that Ascilion has the ability to change the way that things are done clinically and that we can build a significant business around the technology – and this is especially exciting for me.”
