Researchers at Purdue University have designed a tech aimed at making it simpler to deliver cancer therapy to the correct “address” within the body while also making it easy the painful consequences on patients by chemotherapy.
One of the big problems with chemotherapy is that most therapy methods aim on the tumor itself without paying noteworthy attention to the microenvironment nearby the tumor. The new technique is posted in the Small nanotechnology journal.
“The traditional method is analogous to a delivery driver attempting to drop off a package to a specific individual without knowing their exact address,” claimed a professor of physical pharmacy and industrial at Purdue, Yoon Yeo, who is spearheading the research team. “Our new method offers directions to discover the exact address to offer the chemotherapeutic drugs.”
The CDC (Centers for Disease Control and Prevention) reports that every year, almost 650,000 patients suffering from cancer get chemotherapy in the United States in an outpatient oncology clinic.
On a related note, in a main improvement in nanomedicine, a global team of researchers has productively programmed nanorobots in mammals for the first time that potentially contracts tumors by slashing off their supply of blood. Every nanorobot is made from a rectangular and flat DNA sheet of origami that has a size of 90 nanometers x 60 nanometers. Once bound to the surface of tumor blood vessel, the nanorobot was planned to supply its unsuspicious cargo of drug in the very center of the tumor, revealing an enzyme dubbed as thrombin that is responsible for the clotting of blood.
The nanorobots operated quickly, congregating in huge numbers to swiftly surround the tumor just hours post injection. “We have designed the first DNA robotic and completely autonomous system for a targeted and very exact drug design cancer therapy,” claimed Director and Professor at Arizona State University, Hao Yan, to the media in an interview.
