Dr. Bau’s current research interests are in nano and macro-fluidics and electrokinetics with applications in biology and medicine. His group has developed means for the directed positioning of individual molecules and the study of their mechanical and electrical properties; carbon nanopipe-based devices for cell surgery (funded, in part, by the NTI); and components for and fully integrated laboratories on chips for biological studies and disease detection at the point of care.
Carbon-Based Nanopipettes as Cellular Probes: The core group is developing unique, integrated probes that consist of a macroscopic handle made with a standard glass capillary terminating with a carbon nanopipe with a diameter ranging from tens to hundreds of nanometers and a length ranging from microns to tens of microns.
The probe is hollow, facilitating fluid flow through its bore, and electrically conducting, facilitating electrical measurements through its carbon lining. The probe can be used to inject various reagents into cells and to monitor cell membrane potential without causing any harm to the cell. The probe’s tip can be functionalized with proteins, oligonucleotides and nanoparticles. In addition to having superb mechanical properties, the probes are unique in their multifunctional capabilities, allowing for concurrent injection and electrical detection. Although the probes can be used for various applications, the group’s effort currently focuses on cell biology.

OCT showed a decrease of the NFL cyst and the OLD that had also migrated from the subfoveal to a nasal parafoveolar location. The outer layer hole was less obvious, while the Elite White Kris Russell Jersey ILS was persistent but less pronounced (see Figure 3c, d). The patient was under regular follow up. The clinical and OCT picture were unchanged when the patient was last seen at 6 months after presentation.

There was no evidence of PVD or vitreous traction to suggest liquified vitreous to be the cause of the fluid as proposed by Sugar.4 The occurrence of the NFL cyst and its
NTI: Signs of Success
NTI research programs have been extremely successful at publishing in peer-reviewed journals, resulting in more than 820 articles.
In addition, NTI researchers have been awarded more than 200 federal grants totaling more than $150 million.
