Self-assembling Nano-fiber Gel Delivers High Concentrations of Clinically Approved Drugs

23.10.2008
Scientists have developed a new self-assembling hydrogel drug delivery system that is biocompatible, efficient at drug release, and easy to tailor. Importantly, these structures can deliver clinically approved drugs in high concentrations without requiring carriers for the drug or generating toxic components, a problem with hydrogel systems until now.

Two teams of scientists from Harvard-MIT Division of Health Science and Technology at Brigham and Women’s Hospital have developed a new self-assembling hydrogel drug delivery system that is biocompatible, efficient at drug release, and easy to tailor.

Importantly, these structures can deliver clinically approved drugs in high concentrations without requiring carriers for the drug or generating toxic components, a problem with hydrogel systems until now.

The findings, which are now available on Science Direct, will be published in the Nov. 25 issue of Biomaterials.

“This strategy could serve as the platform technology for developing drug-based delivery carriers that can release drugs such as anti-inflammatory agents on demand in response to inflammation, for example,” says Jeffery Karp, MD, instructor of medicine at the HST Center for Biomedical Engineering at the Brigham and Women’s Hospital and a co-corresponding author on this manuscript.

“Converting known, clinically-practicing drugs into amphiphilic molecules which can undergo self-assembly is the key development in our present research; this may eliminate the need for an external carrier for delivering drugs,” says Praveen Kumar Vemula, PhD, research fellow in medicine at Brigham and Women’s Hospital.

“Enzyme triggered gel degradation has been our key strength, which played a major role in developing these delivery vehicles from drugs-based hydrogels,” says another leading investigator Dr. George John who is associate professor at City College of New York. Gregory Cruikshank, another author of the article is at present working in Albert Einstein College of Medicine of Yeshiva University.

This work was supported (in part) by a grant from the City University of New York PSC-CUNY research award program. Brenntag North American provided enzyme samples.

The Harvard-MIT Division of Health Sciences and Technology (HST) brings together the Massachusetts Institute of Technology (MIT), Harvard Medical School (HMS), Harvard University, the Boston area teaching hospitals and an assortment of research centers in a unique collaboration that integrates science, medicine and engineering to solve problems in human health.

Im Focus: A Challenging European Research Project to Develop New Tiny Microscopes

The Institute of Semiconductor Technology and the Institute of Physical and Theoretical Chemistry, both members of the Laboratory for Emerging Nanometrology (LENA), at Technische Universität Braunschweig are partners in a new European research project entitled ChipScope, which aims to develop a completely new and extremely small optical microscope capable of observing the interior of living cells in real time. A consortium of 7 partners from 5 countries will tackle this issue with very ambitious objectives during a four-year research program.

To demonstrate the usefulness of this new scientific tool, at the end of the project the developed chip-sized microscope will be used to observe in real-time...

Im Focus: Giant Magnetic Fields in the Universe

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.

The results will be published on March 22 in the journal „Astronomy & Astrophysics“.

Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...

Im Focus: Tracing down linear ubiquitination

Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.

Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Im Focus: Polymer-coated silicon nanosheets as alternative to graphene: A perfect team for nanoelectronics

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.
