Co-polymer Stabilizers for Pressured Metered Dose Inhalers (pMDIs)

A series of novel co polymer surfactants with the general structure LAmEOnLAm were developed along with a Colloidal Probe Microscopy (CPM) method to optimize the surfactant composition using adhesion forces to improve stabilization of drug dispersions. This expands the range of biomolecules and micronized drug particles that can be formulated with pMDIs....

Nanometer-Sized Drug Delivery Devices (Nanoparticles) that Demonstrate High Encapsulation Efficiency and Sustained Release of Water-Soluble Drugs and their Preparation

WSU researchers have developed a nanoparticle formulation for the encapsulation of hydrophilic drugs with high efficiency. Encapsulation efficiency close to 100% has been achieved. Further these nanoparticles demonstrate sustained release of hydrophilic drugs over a period of weeks (~60-80% of encapsulated drug released over a period of 4 weeks)....

Visual Prostheses Based Upon Fiber-Optic Uncaging of Neurotransmitter Substances

Detailed Description A fiber optic cable may also be used to deliver light. The drug delivery system selectively delivers drugs to various types of neurological cells. In operation a solution of photoactivatable neuro-active drug is delivered to a pre-selected area in vivo and photoactivated in the solution at the pre-selected area to stimulate neurological...

GlyB4 Fusion with Neuregulin Heparin-Targeting Domain to Block Neuregulin Signaling

We have harnessed this natural targeting ability of NRG by fusing the HBD of NRG to soluble HER4. This fusion protein retains high affinity heparin binding to heparin and to cells that express heparan sulfates resulting in a more potent NRG antagonist. In vivo, it is targeted to peripheral nerve segments where it blocks the activity of NRG as a Schwann...

Dual action nanocarrier combining CXCR4 antagonist and polyplex gene delivery for treatment of metastatic cancer and other diseases

Novel bio-reducible polymer compositions which combine the ability to act as a CXCR4 antagonist and simultaneously provide enhanced gene delivery through the formation of inert nanocarrier polyplexes have been developed. As would be expected for biodegradable polymers, the cytotoxicity of these nanocarrier compositions are very low with measured IC50...

Drug-Dendrimer Nanoparticles for Targeted Treatment of Neuroinflammation

Highly effective dendrimer-drug based compositions and methods for treatment have been developed that target neuroinflammation both in the brain and the retina upon intravenous administration. The nanodevices overcome the blood-brain barrier (BBB) and deliver drugs to target cells (activated microglia and astrocytes) producing dramatic therapeutic improvements....
