Medical technology companies to benefit from Picosun biocompatible materials

ESPOO, Finland, November 23, 2021 / PRNewswire / – The Picosun Group has launched a medical materials library consisting of over ten materials designed for atomic layer deposition (ALD) coating and encapsulation in the medical field. ALD coatings are ultra-thin and guarantee hermetic encapsulation of virtually any implanted device.

The library of materials is a reflection of over six years of extensive research and development showing that ALD can impart biocompatibility to a substrate coated with Picosun library materials. Biocompatibility tests were carried out according to ISO standards in accredited third-party laboratories. The tests carried out included, for example, cytotoxicity, antimicrobial activity, skin irritation or sensitization, hemocompatibility, bacterial endotoxins, bioburden and sterilization residues. From the materials tested, Picosun is able to design dozens of different types of end materials according to customer requirements.

The ALD technology offers a dimensionless coating and thus enables the miniaturization of components and devices in the field of electronic implants. Antibacterial function together with excellent barrier properties and excellent corrosion resistance pave the way for the use of the materials in both electronic and orthopedic implants and show a high potential in pharmaceutical packaging. The superior film uniformity and conformance ensure needle-free coverage of even the smallest details of the device.

“The results shown show the undeniable possibilities that ALD is already offering the medical sector today. While the basic surgical principles and technologies have stayed the same for decades, ALD now enables untold applications that potentially improve patient safety and cost-effectiveness by extending the life of implants and reducing side effects, “says Niku Oksala, Professor of surgery at the Tampere University and medical advisor to Picosun.

“The Medical Materials Library from Picosun, which is geared towards the segment of medical device manufacturers, reflects the company’s innovative spirit. I am very pleased that we can flexibly design tailor-made encapsulations according to the needs of our customers. I am particularly proud of our medical customers and partners who are already in preclinical and clinical studies with their ALD-coated devices, “says Juhani Taskinen, Vice President, Medical Business Area of the Picosun Group.
