Students in the DeltaPhase and NanoMedial research teams have successfully created core-sheath nanofibers!  With assistance from Carl Clegg at ra-hart instrument co. and one of the company's coaxial spinnerets, the students were able to design and run several coaxial electrospinning experiments with plans to create phase change textiles and core-sheath medicinal embedded cellular scaffolds.

Craig Johnson at Drexel University performed analysis utilizing a Transmission Electron Microscope to prove that the fibers were core-sheathed!  These images show that the teams successfully core-sheathed their nanofibers!  Next is proving that they can act as viable phase change materials and cellular scaffolds!

Core-Sheath Electrospinning:  A Better Bandage: NanoMedical Solutions (Tom Gerhart, Brian Lawn)

Engineering Academy students, Tom Gerhart and Brian Lawn, have successfully core-sheath electrospun nanofibers today in the lab. 
 This is their first official trial and hope to tune all of the parameters of their experiment.  The ultimate goal of their research this year is to design and test a bandage that will act as an antibacterial core-sheath nanofiber-based cell scaffold that time releases pain medicine to victims with acute traumatic wounds.

Medicinal MicroEncapsulation: Introducing Another Method to Pain Relief

Students in the NanoMedical Research Group successfully microencapsulated medicine, to reduce pain symptoms caused by large wounds. A first for North Penn High School and a first for our future. These vesicles have the potential to become embedded into a polycaprolactone cell scaffold system which will aid in the regeneration of cells. Keep posted for further details.

Electronic Plants: What if...

Engineering Academy Junior, Julia Santos, is currently researching the design and development of conductive plants.  Inspired by research from the
Laboratory of Organic Electronics, Department of Science and Technology, Linköping University and the Department of Forest Genetics and Plant Physiology, Swedish University of Agricultural Sciences in Sweden.

Her initial research began with a tomato plant to experiment with measuring conductivity utilizing our Keithley 2450 Source Meter.

Her research has moved to utilizing roses and she is currently learning about the internal structure of rose stems.  Check back soon for more information!

Bubble Electrospinning:  Another approach to producing polymer nanofibers

Students in the DeltaPhase research team designed an apparatus to create nanofibers from a process known as bubble electrospinning.  The students designed and ran their first experiment and successfully created nanofibers. 

The next step in their endeavor is to analyze their initial results, make modifications and re-run their experiments to improve upon their results.  Check back soon for further updates.
