Passenger Cabin Cultures After Disinfection Fogging. #UV Light #ICUDAS #IUVA

 


The COVID-19 pandemic has made all of us painfully aware of the presence of harmful pathogens aka invisible menaces. Disinfection which is part of the cure we seek, is far from a perfect science. As my microbiologist friend would say "do we want to get rid of all the bugs Kurt?" When I started killing pathogens with my inventions, I thought yes. Now, the answer is absolutely no. While striking the right balance seems to be elusive we should not kid ourselves that some of the solutions being offered are far from the high effectiveness claims being casually tossed around. And we should be vigilant to learn more about disinfection. We are looking for a sweet spot.  And now we have to worry that we are not safe even when people claim to protect us with devices and services.

The attached photo was part of a presentation at a recent ultraviolet light conference held 8th and 9th of December 2020. We are still a ways from getting it right or even defining right in some cases. I apologize for offering no solutions today, just food for thought.

HYPER LIGHT TECHNOLOGIES circa 2017

 





The Hyper Light Story – for LinkedIn by Kurt Garrett, Founder, 2017.

Key words. Hyper Light, Hyper Light Technologies, Hyperlight, Lumagenics, Ultraviolet light, UV

Forward. Today, strong financial support and outstanding third-party contract testing characterize Hyper Light Technologies. The high energy solutions company I have nurtured for now two decades is enjoying superior financial undergirding and animated technical advisors and collaborators. It has taken time and persistence to get here.

DEVELOPMENT OF A BASIC SCIENCE IDEA. My days as a synthetic organic chemist brought me face to face with ultraviolet light used to maintain sterile water for an ophthalmic solution. The orphan drug was owned by Burroughs Wellcome Pharmaceutical Company, my employer. That brief encounter with ultraviolet light would greatly impact my future.

Downsizing Remote Source Lighting International, RSLI, provided me the opportunity to develop some of my ideas. In 1998, I founded a one-man technology incubator called CSMO, Inc.  My corporate laboratory was located at Shaw University in the Robert’s Science Building. To supplement my income, I was employed as a Science Specialist in a local law firm.

My goal was to apply rapid DNA inactivation of high energy UV light to kill microbes on surfaces. I called the device HPUV (high performance ultraviolet light – named after the chemical analysis instrument HPLC). Within three months I postulated that the same system could be used for medical applications to include cancer treatment and a novel vaccine methodology.  That same year, I filed two patent application: 1) an anti-jaundice formulation for the mortuary industry and 2) microbial sterilization using polychromatic light.

A NEW LAMP GIVES NEW POSSIBILITIES. The uniqueness of the lamp design was radically different than conventional low pressure UV lights. I ordered the high pressure lamp from a California supplier and after reviewing the electromagnetic spectra containing an enrichment of 254 nm, I knew it was possible that I could inactivate DNA in pathogens.  The high pressure lamp was compact and easy to use. Insight into the applications and action of mechanism was slow coming but the modification of the lamp to enhance pathogen inactivation energy was mostly simple adjustments.

THE CHRISTMAS GIFT. I conducted initial tests in my garage using microbes isolated from ventilator dust. After obtaining sheep blood plates and instructions from friends at Burroughs Wellcome and ECU Medical School, I grew cultures to be used for my experiments. Working out of my garage, I used a heating blanket to double as an incubator. Within 24 hours the plated dust produced frothing and foul smelling bacteria. Now I had hardy inoculum to test the efficacy of my new lamp, it was Christmas Eve. I spread inoculum on several sheep blood plates, covered half of the plate with heavy card stock and placed the streaked petri dishes under the light in intervals for up to 90 seconds. On Christmas morning I rushed to the garage to find the light exposed half of the petri dish was clearly unchanged and the other side was covered with mucous foul-smelling bacteria. It was indeed Christmas.

BACHENHEIMER EXPERIMENT. Following a helpful lead from a former graduate student, I met Steve Bachenheimer, a microbiologist with specialty in herpes simplex virus (HSVII) research at UNC-CH. Dr. Bachenheimer conducted tests that demonstrated that my system killed a million colonies of HSV in three seconds! When I shared my findings, I could not get funding needed to launch a company. Dr. Bachenheimer was a bright light those days, he agreed to assist me in efforts to gain interest in my vaccine concepts. I slowed development until I could obtain funding to protect the technology. Rather than expose key advantages, I abandoned the UV sterilization patent application after a promising Office Action in 2000. 

Incubating new technologies. I called the new device high pressure UV light (HPUV). The next weeks I spent testing everything I could get my hands on. I was introduced to Dr. Mark Brecker, then chief of Transfusion Medicine at UNC-Chapel Hill. Dr. Brecker informed me about the challenge of bacteria in aphaeresis processing and storage. Dr. Brecker provided Staphylococcus aureus and Klebsiella pneumonae for testing. HPUV killed both pathogens in under 60 seconds, my confidence was growing.

UV Robots. I couldn’t get enough traction to gain a research collaboration in the local area. The few presentations I made to Angel Investors were received poorly or failed to mature.  I have to admit, I wasn’t very savvy, and most scientists were busy with their own ideas guarding precious limited federal funding.  In contrast, interest in HPUV’s promise was highest among housewives, law enforcement and restaurant owners. North Raleigh residents clamored for a portable hand-held disinfection appliance to ease growing fears about germs. The Raleigh Police Department committed to purchase a unit for disinfecting their cruisers and restaurant owners loved the potential for non-residual disinfection of their food preparation surfaces. I raised a few dollars those days among family and friends to keep testing and development going. I treated everything I could get my hands with HPUV, extending the application for use and drawing new concepts all the while building up HPUV intellectual property. Change was on the horizon. I receive a call from my college roommate, and first investor, that Duke Hospitals was featured in the Sunday news paper touting the use of UV robots in the Bone Marrow Center. I was elated. The UNC/Duke Translational Medicine grant revived ultraviolet light use for disinfection. Within six months of the Sunday news story about the UV robots, I signed three university research collaborations that had previously ignored the technology.

HPUV becomes Hyper Light (HPL). After the three University collaborations I met a young VC who was fearless and well connected. We struck a deal in January of 2016 and incorporated Hyper Light, LLC. We agreed that my new investor would provide all the funding I needed for all the applications and I would provide product development and IP. The first thing he wanted to do was change the name from HPUV to something different. HPUV became Hyper Light™, the new name and logo I created suited my new investor. We put a few smart people around the table and even my son, near completion of his PhD degree, interned for the Newco.  Within three months we were sitting with venture firms on Sand Hill in Menlo Park, CA.  After three weeks we left with our business platform and concepts vetted by top business/medical companies experts. One venture group invited Hyper Light to join them in providing a disinfection solution for a leading US endoscope manufacturer. We were encouraged by the Sand Hill VC’s to present the Hyper Light vaccine concept to Bill and Melinda Gates Foundation. We followed their advice. We flew to Portland on the trip back to the east coast. Gates Foundation Investment executive applauded our technology and described a path for us to work together. Gates Foundation Investment offered their external engineering group and their vast IP portfolio for the development cycle that would lead to a vaccine.  Within two months my VC investor faced mounting financial difficulty and a Chapter 11 bankruptcy. In late spring of 2016 I dissolved Hyper Light, LLC and was again looking for new investors. I raised enough money from friends that summer to polish the IP portfolio and file a new patent application in July of 2017. Determined to demonstrate that Hyper Light could generate revenue, I launched two initiatives, a pilot program offering surface cleaning in daycares and a licensing strategy. Within seven months I found a private investment group following advice from a local seasoned attorney. I would offer up The Hyper Light portfolio that included hard surface deep disinfection, cancer treatment, and a vaccine methodology. We agreed to a $3M initial investment for hard surface disinfection. When we have achieved key milestones, our agreement provides for up to $50M of extended investment for the two remaining verticals.  End Part I.
