Kastus Technologies is a nanotechnology company which specializes in Patented Visible Light activated, photocatalytic antimicrobial coatings and additives.[1] Founded in Dublin in 2013, Kastus’ antimicrobial coatings and additives have been in development for over 10 years as part of a collaboration between CREST and Dublin Institute of Technology.[2]


Kastus was founded in 2013 in Dublin following 10 years of collaborative research between the Centre for Research in Engineering Surface Technology (CREST) and Dublin Institute of Technology funded by Kastus CEO John Browne.[3]

In April 2016, Kastus’ team of scientists announced a significant breakthrough in antimicrobial technology which will allow everyday items – such as smartphones and door handles - to be protected against deadly bacteria, including MRSA and E. coli.[4]

In December 2016, Kastus received €1.5m investment from Atlantic Bridge University Fund —a major international investment firm.[5] This funding ensured Kastus could continue to be well-capitalized as it scaled internationally and expanded its customer base.

In January 2017, Kastus launched its industry-defining products at Arab Health in Dubai —the largest healthcare event in the MEMA region. This also saw the launch of its flagship product—Log4+, a patent and novel light-activated product that is 99.99% effective at killing superbugs or inhibiting their growth on surfaces which come into frequent human contact.[6]

In May 2017, Kastus announced that superbug free toilets could be a reality by the end of 2017.[7] As a result of their developments in ceramics, Kastus is likely to be the first real-life application of superbug resistant ceramic toilets and sanitary-ware. This has led to huge interest from the ceramics industry and sanitary-ware producers.

In October 2017, speaking to Silicon Republic, CEO John Browne gave a brief description of how Log4+ works and its applications to mobile devices: "The solution is applied in the factory when the glass or metal is made, and it is permanently there. This is critical because electronic devices are among the most potent carriers of superbugs. You bring your phone everywhere, to the kitchen and even the bathroom, and there are 30 times more bacteria on your phone than on a toilet seat. Our technology adds protection where high-touch surfaces are covered in bacteria. It forms a top-layer surface and uses the indoor light moisture in the air to kill the bacteria.”[8]

In October 2017, the company launched Kastus Metals at Med In Ireland – Ireland’s largest medical technologies event.[9] In November 2017, Kastus signed a deal with British Ceramic Tile (BCT), the largest ceramics and glass tiles manufacturer in the UK. This will see superbug resistant floor and wall tiles on the market in 2018.[10]


Kastus’ Log4+ product is a natural light activated solution which is baked into core production materials during the production process and thus provides a layer of antimicrobial protection which lasts for the lifetime of the product it has been applied to. As it is activated by natural light, Log4+ does not emit any airborne contaminants and therefore is beneficial to the environment.[11] Log4+ can be applied to a range of materials, such as ceramics, glass, metals and plastics, in the final stage of production with 0% interruption to the final product.[12] Log4+ applications are hugely diverse, with opportunities to utilize the product in areas such as medicine and healthcare, food production, public spaces, ATM’s and smartphones.

Awards and Accolades[edit]

Knowledge Transfer Ireland (KTI) Award (Won)[edit]

In March 2017, Kastus was awarded the Spin-out Company Impact Award.[13] The Knowledge Transfer Impact Award is awarded for substantial commercial achievements by knowledge transfer professionals who work in higher education and publicly-funded research organisations. Kastus was recognized for having achieved a “successful and significant event” in the previous calendar year.

Irish Times Innovation Award (Won)[edit]

In October 2017, Kastus received the Overall Prize at The Irish Times Innovation Award, as well as the Life Sciences & Healthcare category award.[14]

Start-up World Cup Regionals (Shortlisted)[edit]

In November 2017, was shortlisted in the Start-up World Cup regional final.[15] The Start-up World Cup is a global initiative developed by FENOX Venture Capital that offers start-ups the opportunity to win $1m funding at the world competition stage.
