Nanofabrication of Bioselective Materials using Diverse Nanolandscapes Displayed on Live Viruses

Petrenko V.A., Olsen E.V., Sykora J.C., Kouzmitcheva G.A., Sorokulova I.B., Brigati J.R., Chen I-H., Chin B.A., Vodyanoy V.J., Auburn University, US

Filamentous phage, such as fd used in this study, are thread-shaped bacterial viruses. Their outer coat is a tube formed by thousands equal copies of the major coat protein pVIII (Figure 1, left). We constructed [...]

Self-Assembly of Fluorescent Silica (glass) Beads

Kievesky Ya., Sokolov I., Clarkson University, US

We report self-assembly of fluorescent silica (glass) bids. The bids are a few microns glass nanoporous particles which contain florescent dyes imbedded in the pores. The pores are self-closed, so the dye does not leak [...]

Fluorescent Silica Beads for Detection of Cervical Cancer

Iyer S., Kievesky Ya., Woodworth C.D., Sokolov I., Clarkson University, US

We present the use of self-assembled fluorescent silica (glass) bids for detection of cervical cancer. The cells from three different individuals (3 normal and 3 tumor) were tested for affinity by using the bids, a [...]

An Chip-based-Instant Protein Micro Array Formation and Detection System

Tseng F-G, Ho C.E., Chen M.H., Chen Y.F., Hung K.Y., Su C-J, Chen M.H., Chen Y.F., Huang H.M., Chieng C-C, National Tsing Hua University, TW

This paper proposes a novel protein micro arrayer employing 3-in-1 chip system, instantly delivering hundreds of biosamples in parallel for disease diagnosis. The 3-in-1chip system included: micro filling chip, micro stamper array and micro bio-reaction [...]

Immunosensing Using Fabricated protein Microarrays

Howell S.W., Inerowicz H.D., Guirl L., Regnier F., Reifenberger R., Purdue University, US

Patterned microarrays of antibodies to specific bacteria were used to perform a series of bacterial immunoassays of E. Coli 0157:H7 and Renibacterium Salmoninarum (RS). Microarrays were fabricated using microcontact printing (MCP) and characterized using scanning [...]
