In this paper we present the results of surface temperature control of silicon nanowires by using fluorescent thermometry at the nanometer scale. Rhodamine B is one of the stable fluorescent molecules, which rely on the characteristic of temperature-dependent change in fluorescent intensity, and it was used for nano-scale surface temperature sensing(More)
A concept of using electrodeposition and microfluidic flow for the fabrication of metal microtubes on a silicon wafer is presented. Microsized holes (2-100 mum) were first etched on a wafer. After depositing a Ti/Cu seed layer on the wafer, electrodeposition of copper was realized. By the use of a water flow through the holes during deposition, clogging of(More)
A simple chromatographic assay for Rab geranylgeranyltransferase (Rab GGTase) has been developed. The method involves separation of the reaction mixture on a Sephadex G-25 superfine minicolumn. Addition of 2-propanol to the assay results in substantial (approximately 90%) decline of formation of noncovalent lipid-protein complexes, increasing(More)
Short peptide ligands were synthesized to selectively capture spores using microcantilever arrays. Our initial studies focused on the capture of Bacillus subtilis (a stimulant of Bacillus anthracis) spores in liquids. A peptide-ligand-functionalized microcantilever array was mounted on a flow cell filled with a B. subtilis suspension while cantilever(More)
We present here preliminary investigations on the use of dried Rhodamine B as a probe for micrometer scale and submicrometer scale temperature measurements. It is shown that even in dry conditions, Rhodamine B maintains a temperature dependent fluorescent intensity. Investigations on its photostability as well as its thermal stability in dry conditions are(More)
