Carbon nanotubes to deliver drug molecules.
Nanotechnology is rapidly developing field in especially engineering and medical sciences. Carbon nanotubes are one of the most studied nanomaterials in material sciences and physics. Although there are limitted number of studies have been performed with carbon nanotubes in medical sciences and pharmacy, to use carbon nanotubes as drug delivery material is still at beginning and at developing s...
متن کاملNanotechnology Meets Plant Biotech- Nology: Carbon Nanotubes Deliver Dna and Incorporate into the Plant Cell Structure
Carbon nanotubes (CNT) can intracellulary traffic through different cellular barriers and deliver biomolecules into living cells. However, their use in plants is limited by the cellulosic wall surrounding the plant cell. Here we show that CNT with immobilized cellulase can serve as an efficient DNA delivery system for plant cells. Tracking the cellular fate of nanotubes revealed two novel pheno...
متن کاملCan Carbon Nanotubes Deliver on Their Promise in Biology? Harnessing Unique Properties for Unparalleled Applications
Carbon nanotubes (CNTs) are cylindrical sheets of hexagonally ordered carbon atoms, giving tubes with diameters on the order of a few nanometers and lengths typically in the micrometer range. They may be single- or multiwalled (SWCNTs and MWCNTs respectively). Since the seminal report of their synthesis in 1991, CNTs have fascinated scientists of all stripes. Physicists have been intrigued by t...

The Amazing and Versatile Carbon – Chemical basis for life With an atomic number of 6, Carbon is the 4th most abundant element in the Universe by mass after (Hydrogen Helium and Oxygen). It forms more compounds that any other element, with almost 10 million pure organic compounds. Abundance, together with the unique diversity of organic compounds and their unusual polymer forming ability at the...
متن کاملCarbon Nanotubes
C is an extraordinary element, considering the diversity of materials it forms. Ranging from sparkling gems to sooty filth, these materials have been studied and used for centuries, and carbon science was long thought to be a mature field. So when a whole new class of carbon materials— the fullerenes, such as C6o— appeared in the last decade, many scientists were surprised. The consequences hav...
