Electrospun fiber is used in a new treatment procedure for a brain tumor.

An unprecedented engineering procedure can deliver a safe, effective dose of medicine for brain tumors without revealing patients to toxic side effects from traditional chemotherapy. Andrew Steckl, the professor of the University of Cincinnati, is working with the researchers from Johns Hopkins University, flourished a new treatment for glioblastoma multiforme, or GBM, that is an invective form of brain cancer. Steckl’s Nanoelectronics Laboratory used an automated fabrication procedure known as coaxial electrospinning to create drug-containing velum. The treatment is spread directly into the part of the brain where the tumor is surgically removed. This study was published in Nature Scientific Reports.

Steckl stated that chemotherapy is an entire-body treatment. The treatment has to go through the blood-brain barrier, which means the whole-body dose the person will get much be much over, and this can be perilous and have toxic side-effects. Steckl is an Ohio Eminent Scholar and professor of electrical engineering in the College of Engineering of UC and Applied Science. Coaxial electrospinning joins two or more materials into a fine fiber that is composed of a core of one material clasped by a sheath of another. This fabrication procedure permits researchers to take advantage of the absolute properties of each element to deliver a potent dose of medicine instantly or over time.

Steckl stated that by choosing the base materials of the fiber and the solidity of the sheath, the rate could be controlled at which these drugs are exempted. The electrospun fibers can swiftly release one drug for short-term treatment such as pain relief or antibiotics when another medication or medicines such as chemotherapy is exempted over a more extended period. Steckl also added that they could yield a very sophisticated drug-release profile. The breakthrough is a continuance of work directed by research partners and co-authors Betty Tyler and Dr. Henry Brem at Johns Hopkins University, who improved a locally administrated wafer treatment in 2003 for brain tumors that are known as Gliadel.
