Using Spherical Nucleic Acids to Track and Treat Disease

Spherical nucleic acids are structures that are made by taking a nanoparticle template and using chemistry to arrange short strands of DNA or RNA on the surface of those particles. The spherical core of the nanoparticle creates a spherical arrangement of DNA or RNA, similar to tiny little balls of nucleic acids.

Low cost technique could fabricate microfluidic devices for biomedical applications

In this work, Dr. Diana and fellow researchers propose a low cost technique able to produce microfluidic devices for biomedical applications. The most common technique to fabricate biomedical microdevices is soft-lithography. However, it is a costly and time-consuming technique. Progress in manufacturing milling tools smaller than 100 µm, has enabled the use of micromilling machines to fabricate microfluidic devices capable of performing cell separation.
