EPJ E Highlight - Better chemo drug adsorption onto targeted delivery capsules

Adsorption of chemo drug onto active carbon with aluminium inclusion

New study demonstrates adsorption of chemotherapy drugs onto active carbon delivery capsule can be enhanced with aluminium atom inclusions

The efficacy of chemotherapy treatment depends on how effectively it reaches cancerous cells. Increasing targeted delivery could mean decreasing side effects. Scientists are enhancing methods of selectively transmitting active chemotherapy agents and reducing their toxicity by encapsulating chemo drugs into active carbon used as the targeted delivery device. In a new study published in EPJ E, Gabriel Román, from the National University of the South, in Bahia Blanca, Argentina, and colleagues have demonstrated that adding minute amounts of aluminium atoms onto activated carbon atoms helps increase the adsorption onto the delivery carbon capsule of a standard chemotherapy drug, called 5-Fluorouracil (5-FU). This drug is typically used for stomach, colorectal, neck and head cancer treatments. This model could lead to more effective and convenient cancer treatments with fewer side effects by encapsulating the chemo drug into the active carbon, so that it can be taken orally.

In this study, the authors examined the adsorption of 5-FU on test surfaces made up of activated carbon alone and a version containing a minute dispersion of aluminium within the activated carbon structure. They relied on molecular modelling simulation to predict and display adsorption configuration and energy changes in the two scenarios.

The authors found that aluminium inclusion increases the adsorption capacity of active carbon. This is because the addition of the metal increases the interactions of the drug with the atoms of the encapsulation material in areas where it is polarised. The electric charges present in some areas of the surface of the drug interact with the charges of the aluminium atoms on the surface of the capsule material. This means they contribute to improving its adsorption properties as less energy is required for the adsorption and the drug is at a shorter distance from the encapsulation material.

This was our first experience of publishing with EPJ Web of Conferences. We contacted the publisher in the middle of September, just one month prior to the Conference, but everything went through smoothly. We have had published MNPS Proceedings with different publishers in the past, and would like to tell that the EPJ Web of Conferences team was probably the best, very quick, helpful and interactive. Typically, we were getting responses from EPJ Web of Conferences team within less than an hour and have had help at every production stage.
We are very thankful to Solange Guenot, Web of Conferences Publishing Editor, and Isabelle Houlbert, Web of Conferences Production Editor, for their support. These ladies are top-level professionals, who made a great contribution to the success of this issue. We are fully satisfied with the publication of the Conference Proceedings and are looking forward to further cooperation. The publication was very fast, easy and of high quality. My colleagues and I strongly recommend EPJ Web of Conferences to anyone, who is interested in quick high-quality publication of conference proceedings.
