Abstract:

Magnetische Nanopartikel (MNP) wurden mit neuen Fettsäurederivaten modifiziert. Auf diese Art und Weise wurden wichtige biologische und organokatalytische Funktionen auf die Oberfläche von magnetischen Nanopartikeln aufgebracht. Das folgende Kapitel präsentiert eine Veränderung von mit Polydopamin (PDA) bedeckten magnetischen Nanopartikeln via CuAAC-Reaktion. Zum Beweis der Wirksamkeit dieser Methode wurden biologische Funktionen wie Biotin, Galaktose oder Dansyl an die magnetischen Nanopartikel über einen 1,2,3-Triazolring gebunden, ebenso Prolin als organokatalytische Einheit.

Abstract:

This Thesis reports the fabrication and characterization of interfaces based on conducting polymers (CPs), which are designed with at least one dimension in the nanometric scale, for bioapplications such as scaffolds for promoting electro-active tissue regeneration, drug delivery systems or passive ion transport membranes. In particular, the development of such platforms is addressed to overcome CPs limitations without compromising their electrochemical and electrical properties. Special attention is placed on evaluating those properties that are known to determine cell-biointerface interactio

Microwave synthesis capable of improving reaction rate, yield and purity is highly desirable in preparing a wide range of biomaterials. Although existing conventional methods have been widely used to fabricate the biomaterial, these methods have various limitations especially time and energy consuming.

Abstract:

Mucin networks are formed by the complexation of bottlebrush-like mucin glycoprotein with other small molecule glycoproteins. These glycoproteins create nanoscale strands that then arrange into a nanoporous mesh. These networks play an important role in ensuring surface hydration, lubricity and barrier protection. In order to understand the functional behavior in mucin networks, it is important to decouple their chemical and physical effects responsible for generating the fundamental property-function relationship. To achieve this goal, we propose to develop a synthetic biomimetic mucin using

Nanodiamonds (NDs) have been demonstrated to be promising tools for the delivery of biomolecules into cellular systems and to act as fluorescent label at the same time.
