To mitigate and circumvent orthopaedic-associated infection, systematic oral and parenteral antibiotic therapy is often used; however, efficacy is limited due to dosing, systemic side-effects, patient compliance, effective delivery, treatment length, and resistant bacteria. A more effective method may be sustained local drug delivery of antibiotics at the wound site, using delivery vehicles tha...

It is therapeutically desirable to effectively deliver ceramide, an antimitogenic and proapoptotic lipid second messenger, to transformed cell types. However, the targeted delivery of cell-permeable ceramide analogs, including C6-ceramide, to cells may be impeded by the hydrophobicity of these bioactive lipids, resulting in reduced efficacy. The objective of this study is to develop and optimiz...

Herein, we report natural chitosan end-capped MCM-41 type MSNPs as novel, dual stimuli, responsive nano-vehicles for controlled anticancer drug delivery. The chitosan nanovalves tightly close the pores of the MSNPs to control premature cargo release under physiological conditions but respond to lysozyme and acidic media to release the trapped cargo.

We show for the first time that stable fluorescent vesicles can be constructed by mixing oppositely-charged carbon quantum dots (CQDs) and simple surfactants in water, and can be potentially used as a new generation of biomarkers and drug delivery vehicles.

Local antibiotic delivery with antibiotic loaded acrylic bone cement has been used extensively in the management of chronic osteomyelitis and implant related infections. Though newer drug delivery vehicles are being investigated, it remains the most widely used local antibiotic delivery vehicle in orthopaedic surgery. Self-made antibiotic loaded bone cement beads, which are cheaper and antibiot...

The novel carriers have been exploited through almost all the routes of administration. Association of drugs with carriers is normally noncovalent, based on collective strength of weak binding forces. Many newer carriers are evolving with the advent of technology and the demand of targeted delivery like microemulsions. Microemulsions are clear, stable, isotropic mixtures of oil, water and surfa...

Dendrimers and telodendrimer micelles represent two new classes of vehicles for drug delivery that have attracted much attention recently. Their structural characterization at the molecular and submolecular level remains a challenge due to the difficulties in reaching high resolution when imaging small particles in their native media. This investigation offers a new approach towards this challe...

Present review highlights various drug delivery systems used for delivery of pharmaceutical agents mainly antibiotics, antineoplastic agents, neuropeptides, and other therapeutic substances through the endothelial capillaries (BBB) for CNS therapeutics. In addition, the use of ultrasound in delivery of therapeutic agents/biomolecules such as proline rich peptides, prodrugs, radiopharmaceuticals...

Calcium phosphates (CaPs) are the most widely used bone substitutes in bone tissue engineering due to their compositional similarities to bone mineral and excellent biocompatibility. In recent years, CaPs, especially hydroxyapatite and tricalcium phosphate, have attracted significant interest in simultaneous use as bone substitute and drug delivery vehicle, adding a new dimension to their appli...

Synthetic polymer materials have been surged to the forefront of research in fields tissue engineering, drug delivery, and biomonitoring recent years. Biodegradable synthetic polymers are increasingly needed as transient substrates for regeneration medicine delivery. In contrast commonly used including polyesters, polylactones, polyanhydrides, poly(propylene fumarates), polyorthoesters, polyure...
