Fullerenes exist everywhere, and particularly where the carbon and the high energy exist. And they exist close to the carbon stars, interstellar space, and places where the lighting has earlier struck and close to the volcano craters. They also form when the gas burns in your household gas cooker and in flame of the regular lighter you can see fullerene production.
Fullerenes also have been found in the places of the carbon rock accumulation. Karelian minerals or schungite have got the special place in such regard. And these rocks, include 80% of the pure carbon, and are two billion years old. Nature of the origin isn’t yet clear. But, one suggestion is it was because of an impact of the big carbon meteorite.
In last some years, fullerenes production and application is actively proposed in the wide variety of areas, or recent developments recommend that most of the applications are practical technologies. But, there is not large‐scale production venture for the commercial fullerenes usage. The high production cost & limited accessibility of fullerenes is the primary obstacle in the Fullerene Market development. The improved flame technology generally leads to the highly feasible process for the mass fullerenes production, as it is the continuous process and make use of inexpensive hydrocarbons as the starting materials.
Photosensitizers in a Photodynamic Therapy
PDT or Photodynamic Therapy is one type of therapy of making use of non-toxic and light sensitive compound that, when it is exposed to light, gets toxic. It is used for targeting the altered & malignant cells. The fullerenes are generally used as the compounds. Fullerenes will get excited on irradiation when the molecules return to the ground state, and they give off the energy that splits oxygen present for generating the singlet oxygen that will get cytotoxic in nature.
Used In Protective Eyewear
To know more, fullerenes have got optical limiting properties. It refers to the ability of decreasing transmittance of the light incident in it. The molecules can be used as the optical limiter that will be used in the protective eyewear & sensors. The optical limiter will just allow light below the threshold to go through and maintain light that is transmitted at the constant level, very much below its intensity that might cause any damage to your eye or sensor.
Thus, it is very important to deliver such molecules with great efficacy and safety. Fullerenes are the class of an inorganic carrier, and these molecules will be preferred since they show the good biocompatibility, higher selectivity, retain biological activity, as well as are small to get diffused.
