Safer Medical Devices with Picosun's Antimicrobial ALD Coatings

Millions of people global live with medical implants, and the trend is towards even more complicated solutions that combine highly cutting-edge microelectronics with miniaturized devices embedded into sensitive areas of the body such as spine, brain, eyes, and heart.

Fremont, CA: Picosun Group, the leading provider of AGILE ALD thin film coating technology and solutions, has reported excellent aseptic properties measured from its ALD materials.

Many ALD oxide coatings deposited with Picosun's processes showed a remarkable decrease of microbial growth and had low values of bacterial endotoxin contamination. The coatings were characterized by an independent third-party laboratory as per ISO 22196:2011 antimicrobial standard as well as ANSI/AAMI ST72:2019 bacterial endotoxin standards. These reports, along with the earlier tests validating the non-cytotoxicity of Picosun's ALD films, prove the safety and aseptic advantages of these materials in medical devices, both implanted as well as external ones.

Millions of people global live with medical implants, and the trend is towards even more complicated solutions that combine highly cutting-edge microelectronics with miniaturized devices embedded into sensitive areas of the body such as eyes, brain, spine, and heart. Protecting these devices from the corrosive environment of the human body and vice versa is of utmost importance considering the correct operation, safety, and lifetime of the implant.

Picosun is the trailblazer in offering medical ALD solutions to device manufacturers. The ultra-thin, biocompatible ALD coatings of Picosun guarantee the hermetic encapsulation of the implanted device, with a fraction of the film thickness in comparison other coating methods, and with superior film durability and uniformity guaranteeing a pinhole-free coverage over even the smallest details of the device. Extended lifetime and operational reliability of the implant decreases the requirement for corrective or replacement surgeries, thus saving expensive hospital stays as well as improving the patient's quality of life. For manufacturers, hermetic protective coating enables utilize of more common base materials, such as stainless steels instead of precious metals, which in turn makes the manufacturing saves costs and processes easier.

"The aseptic properties of our ALD films are so excellent that they surpass even the strictest requirements of the medical implant industry. We are excited to bring our new, advanced medical ALD solutions to the market and help our customers keep spearheading their industries with safer, longer-lasting and user-friendly products," stated Juhani Taskinen, Head of Medical Business Area of Picosun Group.
