Title : Nanotechnology in medicine


Nanotechnology has been a rapidly growing field of advanced science in recent times. Nanotechnology has found many applications in treating infectious diseases induced by viruses, bacteria, protozoan, fungi etc. Nanoparticles are effective against a virus, since a virion is of the same dimension as a nanoparticle. Nanoparticles can attach to SARS COV-2 viruses, disrupting their structure and so kill the virus. A  low risk solution using antibody modified bismuth nanoparticle, in combination with an X-ray dose equivalent  to a chest X-ray specifically, has been shown to kill the common bacterium Pseudomonas aeruginosa in a set up designed to resemble a deep wound in human tissue. Heparin functionalized nanoparticles have been use for targeted delivery of anti-malarial drugs. Heparin is abundant and cheap, compared to treatments that involve antibodies, an important consideration, since malaria is most common in developing countries. A  bone repairing nano-particle paste has been developed that promises faster repair of fractures and breakages. DNA containing two growth genes is encapsulated inside synthetic calcium phosphate nanoparticles. Many medicinal endeavours have seen the use of Nanotechnology. These and other more recent advances in nanotechnology will be presented at this conference.

Audience Take Away:

  • Most of the audience are nanotechnologists and thus can incorporate part of my research in their work or apply them to their work
  • The audience will be more knowledgeable at work in nanotechnology. This research faculty can use part of my research to expand their research. However, they must reference my work. 


Prof. Raymond C. Jagessar obtained his BSc (distinction) in Chemistry/Biology from the University of Guyana (1991) and was assistant lecturer in the Department of Chemistry from (1991-1992). He obtained his PhD from the UK in 1995. He held three Post Doctoral Research Fellowships (PDF) at the University of South Carolina (USA), Wichita State University (USA) and the University of the West Indies during the period, 1996-1999. He has several international awards, amongst them are Chartered Chemist, CChem and Fellow of the Royal Society of Chemistry, FRSC, UK, Research Grants and recently, one of the awardees of the Guyana Innovation Prize, 2021. His research interests are broad, covering the spectrum of Pure and Applied Chemistry, Chemical Biology and Pharmaceutical Chemistry. He has published over 100 research articles, five book chapters, one book and presented at many conferences, locally and internationally. He is currently Professor in Chemistry (Organic and Inorganic) at the University of Guyana (South America), Fellow and President of the Caribbean Academy of Sciences.
