Unlocking melanin's potential for space travel.

We are on a mission to unlock melanin's potential to revolutionize the way we protect from/harness radiation and communicate on our planet and in space.

The success of a civilization depends on the materials used to build it. Melanin-based biomaterials can aid humans to become a space faring civilization.

MelaTech was founded in 2017 by scientists with a passion for melanin biology and biotech applications to improve human life.


Remarkable polymers with unique physicochemical properties and commercial applications in radiation shielding/countermeasures, energy harvesting, bioelectronics, obscurants, bioremediation, and many other fields.

We specialize in fungal melanins capable of shielding various types of ionizing radiation, capturing heat from the entire solar irradiance spectrum, and exhibiting superior thermal stability as compared to synthetic melanin analogs.

MelaTech R&D

MelaTech specializes in the large-scale production of melanins and development of melanin-based biomaterials for coatings, clothing, infrastructure, and much more.

Radiation shielding for use in space exploration and colonization, radiation hardening electronics, and developing protective barriers for humans. Improved radiation shielding materials could mitigate future disasters like the Fukishima and Chernobyl incidents.

Harnessing melanin's ability to broadly absorb solar radiation has potential for improving passive heat capture systems for cold climates.

Melanin has fascinating electrical properties which have already been demonstrated in the construction of melanin batteries. Coupled with solar absorption and radiation shielding there are many unique applications for bioelectronics.

Quigly Dragotakes

Chief Scientific Officer

Ithaca College, B.S. (Biochemistry, 2014)
Johns Hopkins University Bloomberg School of Public Health, Ph.D. (Molecular Microbiology and Immunology, 2020)
Mr. Dragotakes received his Bachelor of Science in Biochemistry from Ithaca College in 2014 where he studied bacterial quorum sensing as well as gene compensation. Following graduation, he spent two years studying Alzheimer's Disease pathology as a research assistant in the Greengard Laboratory of Molecular and Cellular Neuroscience at The Rockefeller University before beginning his doctoral studies. His Ph.D. research focused on host-pathogen interactions of phagolysosome resident Cryptococcus neoformans.

Quigly has broad technical expertise ranging from molecular biology to biochemistry and computer programming. He established MelaTech's 3D printing technology, and was responsible for generating the melanin and designing the samples for the MISSE 12 and 13 missions. As a jack-of-all-trades Quigly was the clear choice of CSO, quick to learn new techniques across a variety of fields and competent at applying that knowledge to efficiently generate quality results. He has already pioneered multiple patented melanin biotechnologies.

Join the Melatech Team, Win a Scholarship

The MelaTech Young Talent Scholarship/Internship is committed to supporting under-represented STEM students for short-term internships at our R&D facility. Scholars will carry out basic and applied research work related to melanins and the development of novel melanin-based biomaterials for applications in space exploration, environment conservation, and national defense. Previous R&D experience is a plus but not as important as passion, desire to learn, and hard work. Interested individuals can write an email to info@melatech.space with a short cover letter explaining why you are interested in working with us.
