Abstract In this study, nanohybrid materials consisting of graphene oxide (GO), β‑cyclodextrin (CD) and poly(amido amine) dendrimer (DEN) were successfully prepared by covalent bonding. GO-CD and GO-CD-DEN were found to be potential nanocarriers for anticancer drugs including chemotherapeutics (doxorubicin (DOX), camptothecin (CPT)) and photosensitizer (protoporphyrin IX (PpIX)). GO-CD possessed 1.2 times higher DOX-loading capacity than GO due to inclusion of additional DOX to the CD. The drug ...

Previously synthesized amphiphilic diblock copolymers with pendant dendron moieties have been investigated for their potential use as drug carriers to improve the delivery of an anticancer drug to human breast cancer cells. Diblock copolymer (P71 D3 )-based micelles effectively encapsulate the doxorubicin (DOX) with a high drug-loading capacity (≈95%, 104 DOX molecules per micelle), which is approximately double the amount of drug loaded into the diblock copolymer (P296 D1 ) vesicles. DOX releas...

Abstract Hybrid carriers were successfully synthesized by chemically binding OH-terminated fourth generation poly(amido amine) dendrimer and folic acid on graphene oxide (GO) with a size of 100 nm, and their drug carrier ability was compared with hybrids of 1500 nm GO. The small hybrid carriers possessed a 1.3 times lower loading capacity (1.43 g/g(GO)) for doxorubicin (DOX) than the large hybrid carriers. However, the amount (86%) of DOX released at pH 5.5 from the small hybrids after 72 h was ...

Abstract Three ultrathin films consisting of dendrimer self-assembled monolayer (SAM), silica particle/dendrimer SAM and silica particles have been prepared on glass surface to develop solvo-affinity and surface roughness and to elucidate the anti-fingerprint effect. The solvo-affinity and surface roughness of the coated films on glass surface were characterized by contact angle measurement and atomic force microscope. The results showed that the fabrication of dendrimer SAM on glass revealed th...

Abstract Hydroxyl-terminated fourth generation poly(amido amine) dendrimer and folic acid were chemically bound on graphene oxide. The resultant hybrids exhibited one-photon and two-photon fluorescence emission, since the excitation irradiation at 390 and 780 nm on the hybrids brought a fluorescence emission in the visible region around 450 nm. In addition, the photocytotoxicity study revealed that under the two-photon excitation at 780 nm, the hybrids can absorb near-infrared light and generate...

Abstract Self-assembled monolayers of organosiloxanes and their hybrids with different functionalities were successfully fabricated on glass surfaces by sol–gel technique. Contact angles with water and hexadecane revealed that the examined organosiloxanes can be classified into hydrophobic/oleophilic and hydrophobic/oleophobic molecules, and the latter character can be called amphiphobic. Since contact angles of amphiphobic oleic acid, a main component of finger print, is high for amphiphobic or...

Abstract The presented approach provides the advanced development of effective, rapid, and versatile electrochemical sensors for a small amount of analytes on potential, cheap, and disposable printed chips. The electrocatalytic activity of this biosensor revealed the feasible detection of hydrogen peroxide at low potential (∼0.09 V) and the detection of a biocontaminant inhibitor (organophosphorus pesticide) in a wide range of concentrations. This efficiency comes from the chemical immobilizatio...

Electrochemical sensors consisting of electrodes loaded with carbon nanotubes and Pt nanoparticles (PtNPs) protected by dendrimers have been developed using a facile method to fabricate them on two types of disposable electrochemical printed chips with a screen-printed circular gold or a screen-printed circular glassy carbon working electrode. The electrochemical performance of these sensors in the oxidation of methanol was investigated by cyclic voltammetry. It was revealed that such sensors po...

Pt nanoparticles (PtNPs) were synthesized in the presence of a NH2-terminated fourth generation poly(amido amine) (PAMAM) dendrimer as a stabilizer at different molar ratios (M : D) of metal precursor to amine terminal group of dendrimer. Subsequently, PtNPs protected by dendrimers (DENPtNPs) were covalently immobilized on multiwalled carbon nanotubes (MWCNTs) by using a condensing agent for amide bond formation between acid-treated MWCNTs and DENPtNPs and the product CNT/DENPtNPs were character...
