Gold Encapsulated RNA and Lasers to Fight Cancer

New research at UCSB is investigating using RNA-filled gold nanocapsules with a peptide-lipid coating to fight cancer cells. The nanoparticles are introduced into the cell using a pulsed near-infrared laser. From Nanowerk: “The scientists used cancer cells from mice, and grew them in culture. They then introduced gold nanoshells, with a peptide-lipid coating, that encapsulated […]

NASA Report on Space Station Drug Microencapsulation Research

NASA has released a report on their investigations into microencapsulation of targeted cancer drugs. This research was conducted in space, on the International Space Station. Here’s a link (pdf) to the full NASA ISS research report. And here’s a blub from the press release: “Another experiment produced a potential medical advance, demonstrating a new and […]

Preparation of nearly monodisperse microcapsules with controlled morphology by in situ polymerization of a shell layer

Abstract: Nearly monodisperse microcapsules with controllable porous surface morphologies were prepared by the in situ polymerization of melamine and formaldehyde with a template of nonionic surfactant micelles above the cloud point, inside which normal alkanes can be either encapsulated as phase change material or removed to obtain porous hollow spheres. The experimental results indicate that […]

First Aid for Electric Circuits

Researchers at UIUC have developed microcapsules of carbon nanotubes that are resistive in electric circuits when undisturbed, but become conductive when ruptured. This technology has the potential to make more failsafe circuits and more reliable batteries. From the RSC article: Jeffrey Moore, at the University of Illinois at Urbana-Champaign, and colleagues made microcapsules with robust […]

BioBullets To Combat Invasive Zebra Mussel

A Cambridge based company called BioBullets has developed an encapsulated poison of the same name intended to control the zebra mussel, and invasive bivalve that is clogging waterways worldwide. From a Business Weekly article: Dr David Aldridge of the University of Cambridge’s Zoology department says that his company, BioBullets received approval to use its potassium […]

Self-Healing Metal Coating Developed With Nanocapsules

Researchers at the University of Duisburg-Essen in Germany have developed a self-healing nanocapsule coating for metal that will prevent corrosion. This is the first such coating that can be electroplated onto a metal surface. From the Technology Review article: The self-healing metal can be electroplated, which opens up applications in construction, car manufacturing, and other […]

Using a Microsphere Collagen Filler to Reduce Wrinkles

A press release from the American Institute for Plastic Surgery discusses their use of a microsphere-enhanced collagen dermal filler to reduce wrinkles: Artefill is a simple, in-office procedure that takes approximately fifteen minutes to complete. A patient is injected with the product similar to other dermal fillers with the key difference being its lasting effect. […]

DEK’s DirEKt Ball Placement Technology Advances toward Microsphere Capability

From a DEK press release: Extending its capabilities for placing solder spheres at high speed, DEK’s proven DirEKt Ball Placement(TM) process now enables accurate solder sphere deposition for spheres as small as 200µm in diameter with pitches as tight as 300µm. With the ability to achieve this accuracy and precision at a first pass yield […]

Microencapsulated Drugs Developed in Outer Space

In an article on the research that takes place on the International Space Station, a NASA scientist discusses a patented drug microencapsulation system that was developed aboard the Space Station. Their targeted microcapsule research was conducted on prostate cancer in mice. From the article: “One challenge we have is that it takes time for the […]

Tehran University Develops Nanocapsule Drug Release Methods

Iranian chemists at Tehran University have been experimenting with drug release using various types of nanocapsules. Recently they have developed a polymer nanocapsule for administering Penicillin-G. From the article at Farsnews: “Among the present nanoparticles, nanocapsules and micelle nanoparticles are more effective. Micelle nanoparticles release the drug in the body slowly, because of their interaction […]
