Medical technology companies to benefit from biocompatible materials

Picosun Group has launched a Medical Materials Library consisting of over ten materials intended for medical-related coating and encapsulation with Atomic Layer Deposition (ALD).

 ALD coatings are ultra-thin, and they guarantee hermetic encapsulation of virtually any implanted device.

The materials library is a reflection of over six years extensive research and development that shows ALD can render biocompatibility to a substrate coated with Picosun library materials. Biocompatibility tests were carried out according to ISO standards in accredited third-party laboratories.

The performed tests included for example cytotoxicity, antimicrobial activity, skin irritation or sensitisation, hemocompatibility, bacterial endotoxins, bioburden and sterilisation residuals.From the tested materials Picosun is able to design tens of different types of end materials according to customer needs.

ALD technology provides dimensionless coating thus enabling miniaturisation of components and devices in the field of electronic implants. Antibacterial function together with excellent barrier properties and outstanding corrosion resistance pave the way for using the materials both in electronic and orthopedic implants and show high potential in pharmaceutical packaging. The superior film uniformity and conformality ensure a pinhole-free coverage over even the smallest details of the device.

“The demonstrated results show the undisputable opportunities ALD offers to the medical sector already today. While the basic surgical principles and technologies have remained the same for decades, now ALD enables unforeseen applications potentially improving patient safety and cost-effectiveness by extending implant durability and reducing adverse effects”, said Niku Oksala, Professor of Surgery at Tampere University and Medical Advisor for Picosun.

“Picosun’s Medical Materials Library targeted to the medical device manufacturer segment reflects the innovative spirit of the company. I’m really excited over the fact that we are able to flexibly design tailored encapsulations according to our customers’ needs. I’m especially proud of our medical customers and partners who are already in pre-clinical and clinical trials with their ALD coated devices”, added Juhani Taskinen, Vice President, Medical Business Area of Picosun Group.
