Cytotoxic drugs or therapeutic DNA for targeted chemotherapy is attached by functionalizing the polymer or metal coating to correct a genetic defect.
The surface coating utilizes the strong affinity between AuNPs and thiol groups, so the existing PAMAM cover prevented the further coating of PAMAM on the surface, leading to the single layer of surface coating and functionalizing the particle surface with abundant amino groups.
To test the stability of the functionalizing coating, the scaffolds were incubated for 24 h at 37°C in physiologic buffer and then analysed by fluorescence microscopy and FTIR.
Thus, controlling the thickness of the polymer coating on the CNTs plays an important role in functionalizing the CNTs.
An increase in surface charge was observed when functionalizing the nanoshells with the Br-initiator molecule (−48.5 mV for bare nanoshells vs −27.0 mV for initiator-functionalized nanoshells), but addition of the hydrogel coating shielded the initiator and returned the particles to a more negative state, as shown in Figure 2C.
A very recent study described a novel nanocarrier system comprising lipidic emulsomes and S-layer (fusion) proteins as functionalizing tools coating the surface (Ücisik et al., 2013b).
In the present study a structural characterization and in vitro cell-biological evaluation was performed on polycaprolactone (PCL) scaffolds that were produced by the additive manufacturing technique selective laser sintering (SLS), followed by a plasma-based surface modification technique, either non-thermal oxygen plasma or double protein coating, to functionalize the PCL scaffold surfaces.
To improve the CNT properties, nanotubes have been treated in different ways, such as functionalizing, coating, and filling the pristine nanotubes [1, 5, 15].
In general, MNPs are coated with a selected material to enhance their colloidal stability and biocompatibility or to offer them the capacity to functionalize the surface, like in the case of a coating of silica (Si( {text{O}}_{2} )) (Rittikulsittichai et al. 2013).
Methods to functionalize the surface of PEGDA microbeads (acrylic acid incorporation, polydopamine coating) reported thus far quench the fluorescence of UCNPs.
The surface of commercially-available activated carbon (AC) was functionalized through the TiO2 coating and sulfonation, and the resulting powder was evaluated as a capacitive deionization (CDI) electrode.
