Dr. Ryan Hayes is researching signal amplification and compositional analysis of nanotechnology materials based on dendrimers. Dendrimers are unique nano-sized polymer materials that provide high concentration of functional groups localized on the surface of these macromolecules. The orientation and presentation of functional groups lead to new properties but also increase the difficulty of analysis using standard techniques. Dr. Hayes is developing new methods of analysis to improve and speed the characterization of dendrimers. In addition, Dr. Hayes is looking into new uses of dendrimers for enhancing optical signals for the detection of various disease states. Dr. Hayes has published articles in the area of photoinduced electron transfer involving novel donor-acceptor systems within macromolecular and nucleic acid structures.
Dr. Hayes has spent nearly a decade working in industry. His experience includes business development, patent portfolio management, and scale-up of chemical-based technologies within the life science reagent, personal care, agricultural, coatings, and polymer additive industries. Dr. Hayes was Director of Business Development for 4.5 years with Dendritic Nanotechnologies (DNT) located in Mt. Pleasant, MI before accepting the teaching responsibilities at Andrews University. Before DNT, he was employed as a research scientist at Lynntech, Inc. in College Station, TX where he assisted with numerous projects to develop and commercial new chemical sensing technologies. Ryan is married to a microbiologist named Suzi, and they have three young children: Carter, Christiana, and Cadance.
Dr. Hayes teaches General Chemistry (CHEM131 & CHEM132) along with Instrumental Analysis (CHEM430) in the Spring.
Dr. Hayes' research activities include the synthesis and analysis of dendrimers which are highly functional polymers with many new properties for medicine, materials, and modern technology. These modern marvels of nanometer dimensions may change the way treatment and diagnostic molecules are administered to improve safety and efficacy. He has involved many undergraduates in his research since 2009 thanks to the ndrews University Undergraduate Research Scholarship program.
Dr. Hayes' research group also looks at finding potentially carcincogenic molecules formed in the burning of plant-based amino acids. There is a class of carcinogenic molecules that form from the burning of creatine and other amino acids called Heterocylice Amines (HCA). These creatine-based HCA's are well known and characterized from the burning of fish and meat. Argninine, commonly found in plant based proteins such as soy, has a similar chemical structure to creatine and previous research has demonstrated that it might also be responsible for forming mutagenic HCAs. No one has identified the chemical structures of a arginine-based HCAs at this point so the Hayes group is using prep-HPLC, NMR, Mass Spectroscopy, and the AMES test to seek out and identify these potentially new class of carcinogens.
Dr. Hayes is also using absorption and emission spectroscopies to characterize and analyze a variety of chemicals and chemical processes.
