Methods & Results from the Cambridge Inkjet Research Centre

Hoath S.D., Martin G.D., Hutchings I.M., University of Cambridge UK, UK

We outline the methods and tools of fluid characterization, drop visualization and drop formation physics that are used at Cambridge. We present recent results and interpretation for drop on demand inkjet printing of some model [...]

Curvilinear Waveforms for Fluid Dispensing

Clark J., Zebra Technologies, US

Piezoelectric micropipettes, a type of drop -on-demand ink jet microdispenser, are typically driven by repetitively pulsed waveforms to cause fluid ejection through a small orifice. To study the effect of drive waveform shape on drop [...]

Electrohydrodynamic Micro-droplet Generation on Both Conducting and Non-conducting Surfaces by Electric Induction

Lee B-S, Lee J-G, Lee B-S, Lee J-G, Cho H.-J., Huh N., Ko C., Samsung Advanced Institute of Technology, KR

There is a rapid growing need of the drop-based delivery of small quantities of bio-functional materials, such as cells. We report a brand-new printing method to generate a single droplet in the range of pL [...]

Magnetic Nano Particles for Diagnostics

Nguyen K.C., Pham V.H., Do S.T., Tieu D.T., SAIGON HI TECH PARK, VN

Magnetic Nano Particles (MNP) for diagnostics had been fabricated by coating the particle ‘s surface with specific coupling agents . This agent allows the pulling the virus containing DNA and/or RNA molecules off the patient [...]

SERS Gold Nanoparticles for Cancer Surface Marker Detection

Nguyen C.T., Nguyen J., Nguyen C.T., Nguyen J., Rutledge S., Wang C., Walker G.C., University of Toronto, CA

Surface Enhanced Raman Scattering (SERS) gold nanoparticles may provide novel optical tags for cellular analysis. Currently, cell markers are mostly assessed by fluorescence labeling using flow cytometry. However, fluorescence dyes are usually limited to 4-5 [...]

Photothermal Characteristics study of PEGylated Gold Nanorods

Shih T-Y, Lin J-T., Tien C.C., Tseng P-L, Chen Y-H, Industrial Technology Research Institute, TW

Gold nanorods have a growing role in a diversity of medical applications especially in the area of hyperthermal therapy of tumor. Since localized temperature rising by laser irritation gold nanorods at near-IR frequency can induce [...]

Fluorescence Based Specific PNA-DNA Binding Characterization on nano-FET DNA Device Surface

Rastogi S.K., Mishra N.N., Finaloski B., Cameron E., Maki W., Postdoc Researcher, US

A novel sequence of peptide nucleic acid (PNA; beta-Ala-(T10)-beta-Ala-NH2) containing ten thymine monomers and beta-alanine amino acid at both (C and N) terminal of main chain was synthesized manually using solid phase tBoc peptide chemistry. [...]

Monitoring of the major blood vessels supplying head and brain (carotid arteries) contactlessly

Kaminska B., Simon Fraser University, CA

An apparatus for measuring Carotid Arteries movement without physically connecting electrodes or other sensors to the body was developed. The measurement system was implemented to simultaneously monitor the Carotid Arteries and ECG in order to [...]

Relaxation Time Constants of Nanometals in Human Tissues and Clinical Applications

Sharma A., Sharma R., Sharma A., Sharma R., Center of Nanotechnology, IN

The metals are in abundance in human body in biofluids, blood, cerebrospinal fluid, saliva, lymph. These metals are found in free and bound forms in each tissue and their amount is tissue specific. The mechanism [...]
