The polymer is a very long molecule formed by the repetition of many monomers. These are molecules that can be linked to one another forming a chain. The best way to write a polymer is to simply write the monomer, put it in brackets, and define the number of monomers it's composed of. When we link to get the two polymers that are made from different starting monomers, we can combine their respective physical and clinical properties. These are called blockopolimers and have special behavior under certain conditions. One specific type of blockopolimers are those formed by a hydrophobic polymer joined together with a hydrophilic one. These are called antifilic blockopolimers, and it's interesting to know what happens once they're placed inside water. The hydrophobic block doesn't want to be in contact with water so it will coel up. When monomers are present, they will screen each other's hydrophobic block self-assembling into a myself. The three most common micellum or phyloges are spherical by layer and elongated, each of which depends on the starting block length of the polymers used. They are characterized respectively by their diameters, their thickness, and their length. We can direct the assembly of micellums by confining the polymer in a very small volume. This is done by dissolving the polymer into a volatile solvent forming an evulsion of the solution with water and letting the solvent evaporate, effectively confining the polymer into very small droplets. This little bit closer at what happens in these small droplets. The antifilic blockopolimers will want to be on the surface of the drops so that the hydrophilic part can be in water and the hydrophobic one can be in the chloroform. Since these droplets are evaporating, they won't be enough space for all the polymers to sit there. This triggers this phenomenon, cause spontaneous emulsification, which causes the formation of long fingers, which will then break up into micellums. Let's take a look at this happening in a video recorded with a fluorescent microscope. In this video you can see the chloroform droplets in black, which undergoes spontaneous emulsification. They will break up into smaller droplets and form very long fingers from their surfaces. These very long fingers will then become more like micellums while the chloroform is completely evaporated. This is part of my PhD project in which I studied the formation of the micellums. I characterized them. I loved them with radioactive particles. And I studied how they behave and contact with cancer cells. In order to characterize the stiffness of the micellums, we developed a technique in which perform nano-3-point bending tests. My project, called Tracing Tree, takes place in the Institute of Shalsadram and collaboration of the University of Delft and is part of the Mediculean Actions.
