Applications of our products in Biotechnology field
C60
Description
The C60 fullerene, thanks to its small size, can easily cross the so-called blood-brain barrier. This property can lead to numerous medical applications, especially in the field of nanomedicines, through the implementation of new active compounds that could be used by the brain.
The molecule can act as a semiconductor, conductor and superconductor under specific conditions. Fullerenes can display the photochromic effect, which is a change in light transmission based on intensity.Ability to form compounds with many different sorts of material including the ability to retain other substances inside the molecule and the ability to absorb free radicals.
Fullerenes are relatively safe and inert, and yet have properties that allow the substance to create active derivatives.
Advantages
Solvent-free
Environmentally friendly synthesis using renewable energy
(hydroelectric powered plant in Quebec)
Applications
Treatment of various neuronal problems.
Development of new drugs for the brain, associating its antioxidant and antiaggregant properties.
Biomedical applications, like the design of high-performance MRI contrast agents and X-ray imaging contrastagents. [1] [2]
Light-activated antimicrobial agents. [3]
Used as a carrier for gene and drug delivery systems.
They are used for serum protein profiling as MELDI material for biomarker discovery.
Potential antiviral activity, which has strong implications on the treatment of HIV-infection.
Anti-aging agent in the cosmetic sector.
Fullerenes can be made to be absorbed by HeLa cells. Recent experiments using HeLa cells in cancer research involves the development of new photosensitizers with increased ability to be absorbed by cancer cells and still trigger cell death. It is also important that a new photosensitizer does not stay in the body for a long time to prevent unwanted cell damage. [4]

Fullerenol C60
Description
Many of the proposed fullerene applications are to be practical technologies in a wide range of areas such as IT devices, diagnostics, pharmaceuticals, environmental, and energy industries. The direct application of fullerene and their derivatives to biological targets is now yielding promising applications in medicine.
Such attention to them is caused by unique chemical and physical properties of the fullerene core, including their photodynamic properties. The hydrophobic spheroid and the radical sponge character of fullerene are responsible for the activity in different fields.
Advantages
Solvent-free
Green chemistry
Environmentally friendly synthesis using renewable energy
(hydroelectric powered plant in Quebec)
Applications
Antimicrobial activity.
Carrier for gene and drug delivery systems.
Pro-oxidants.
Cytotoxic or protective effect respectively against cancer cells or healthy cells.
Transfer of contrast agents or in drug transport.
Protect neurons in the particular areas of the brain.
Application in neuroscience.
Diagnostic application.
In the future provide a solid alternative to currently used pharmacological methods in chemotherapy, treatment of neurodegenerative diseases and radiobiology.
