Abstract

 DRUG DELIVERY IS AN INTERDISCIPLINARY AND INDEPENDENT FIELD OF RESEARCH THAT IS GAINING THE ATTENTION OF PHARMACEUTICAL RESEARCHERS, MEDICAL DOCTORS AND INDUSTRY. A SAFE AND TARGETED DRUG DELIVERY COULD IMPROVE THE PERFORMANCE OF SOME CLASSIC MEDICINES ALREADY ON THE MARKET, AND MOREOVER, WILL HAVE IMPLICATIONS FOR THE DEVELOPMENT AND SUCCESS OF NEW THERAPEUTIC STRATEGIES SUCH AS ANTICANCER DRUG DELIVERY, PEPTIDE AND PROTEIN DELIVERY AND GENE THERAPY. NANOTUBES (NTS) HAVE BEEN DEVELOPED AS AN IMPORTANT STRATEGY TO DELIVER CONVENTIONAL DRUGS, RECOMBINANT PROTEINS, VACCINES AND MORE RECENTLY, DRUGDELIVERY SYSTEMS MODIFY THE KINETICS, BODY DISTRIBUTION AND DRUG RELEASE OF AN ASSOCIATED DRUG. THIS RESEARCH FOCUSES ON THE POTENTIAL OF NANOTECHNOLOGY IN MEDICINE. TITANIUM DIOXIDE NANOTUBE ARRAYS (TNT) USED AS DRUG-CARRIES WAS PREPARED BY SELF-ORDERING ELECTROCHEMICAL ANODIZATION [1]. BACTERIAL INFECTION, EXTENSIVE INFLAMMATION AND POOR OSSEOINTEGRATION HAVE BEEN IDENTIFIED AS THE MAJOR REASONS FOR ORTHOPAEDIC IMPLANT FAILURES BASED ON TITANIUM. CREATING IMPLANTS WITH DRUG-ELUTING PROPERTIES TO LOCALLY DELIVER DRUGS IS AN APPEALING WAY TO ADDRESS SOME OF THESE PROBLEMS. TO IMPROVE PROPERTIES OF TITANIUM FOR ORTHOPAEDIC APPLICATIONS [2]. NANOTUBE ARRAYS ON TITANIUM SURFACES WERE FABRICATED BY ANODIZATION METHODS AND THEIR POTENTIAL FOR STORAGE AND RELEASE OF DRUGS WAS EVALUATED. THE TREATMENT OF THE TI SURFACES IN NH4F/ETHYLENE GLYCOL ELECTROLYTELED TO THE FORMATION OF TIO2 NANOTUBES. THE PREPARED TNT-TI SUBSTRATES WERE LOADED WITH DRUG VIA A SIMPLE METHOD, PUTTING DRUG SOLUTION AND DRYING IT [3]. DRUGRELEASE EXPERIMENTS WITH THE MODEL ANTIBIOTIC CIPROFLOXACIN. SIGNIFICANT SURFACE-DEPENDENT DIFFERENCES IN THE RELEASE KINETICS OF CIPROFLOXACIN WERE OBSERVED. THE MORPHOLOGICAL AND CHEMICAL STRUCTURES OF TIO2 FILMS WERE CHARACTERIZED USINGSCANNING ELECTRON MICROSCOPY (SEM).THE AMOUNT OF THE DRUG WAS DETERMINED BY UV-VIS SPECTROSCOPY. THERE WAS A LINEAR RELATION BETWEEN ABSORPTION AND CONCENTRATION OF THE DRUG. ALL THE MEASURING WAS DETERMINED IN PHOSPHATE BUFFERED SALINE.
