• Microfluidic approach to genotyping human platelet antigens

Publication Year: 2012, Page(s):33 - 39
| | PDF (333 KB)

Centralised laboratories routinely determine blood types by serological and molecular methods. Current practices have limitations in terms of cost, time and accessibility. Miniaturised microfluidic platforms offer an alternative to conventional genotyping methods, since they consume fewer reagents, provide faster analysis and allow for complete integration and automation. As these lab-on-a-chip ... View full abstract»

• Effects of dry ice on gas permeability of nano-silverimpregnated Populus nigra and Fagus orientalis

Publication Year: 2012, Page(s):40 - 44
| | PDF (258 KB)

Effects of dry-ice treatment (frozen CO2 at -78.5-C) on gas permeability of untreated and nano-silver-impregnated poplar and beech specimens were studied here on the basis of their biological structure and woody mass as well as their vessel element types. A 200-ppm aqueous dispersion of silver nano-particles was used for impregnation; the size range of silver nano-particles was 20-80-nm... View full abstract»

• Mimicking the biological olfactory system: a Portable electronic Mucosa

Publication Year: 2012, Page(s):45 - 51
Cited by:  Papers (1)
| | PDF (602 KB)

In this study the authors report on the development of a new type of electronic nose (e-nose) instrument, which the authors refer to as the Portable electronic Mucosa (PeM) as a continuation of previous research. It is designed to mimic the human nose by taking significant biological features and replicating them electronically. The term electronic mucosa or simply e-mucosa was used because our e-...

• Immobilisation of heparin on bacterial cellulosechitosan nano-fibres surfaces via the cross-linking technique

Publication Year: 2012, Page(s):52 - 57
| | PDF (700 KB)

In recent years, bacterial cellulose (BC) has been fabricated in tubular shape as scaffold for vascular tissue engineering. However, in order to improve the blood compatibility and regenerative ability of BC, BC nano-fibres should be cross-linked with some materials which can prevent the formation of blood clot. In this work, a novel BC-chitosan (CS)/heparin (Hep) composite was prepared. Scanning ... View full abstract»

• Biosynthesis of bismuth nanoparticles using serratia marcescens isolated from the Caspian Sea and their characterisation

Publication Year: 2012, Page(s):58 - 62
| | PDF (360 KB)

Today, synthesis of nanoparticles (NPs) using micro-organisms has been receiving increasing attention. In this investigation, a bismuth-reducing bacterium was isolated from the Caspian Sea in Northern Iran and was used for intracellular biosynthesis of elemental bismuth NPs. This isolate was identified as non-pigmented Serratia marcescens using conventional identification assays and the 16s rDNA f... View full abstract»

• Nanochannels: biological channel analogues

Publication Year: 2012, Page(s):63 - 70
| | PDF (243 KB)

The flux of ions across the biological membrane is a central activity to many cellular processes, from conduction of nerve impulse to the apoptosis. Traffic of ions or molecules across the membrane and organelles is governed by natural machines of great precision; ion channels, a special class of proteins, reside in the biological membranes. Recent studies in the field of nanoscience have concentr... View full abstract»

• Design of a bioprocess to produce silver nanoparticles

Publication Year: 2012, Page(s):71 - 75
| | PDF (437 KB)

The development of reliable processes for the synthesis of silver nanomaterials is an important aspect of current nanotechnology research. In this work, silver nanoparticles were produced in a bioreactor by Escherichia coli (E. coli). For this purpose, a process was designed and silver nanoparticles at a scale larger than laboratorial scale were produced by considering optimum condit... View full abstract»

• Fmoc-Cl fluorescent determination for amino groups of nanomaterial science

Publication Year: 2012, Page(s):76 - 80
| | PDF (339 KB)

With the wide application of nanomaterials, the quantification of functional groups on nanomaterial surface becomes more and more necessary. A heterogeneous 9-fluorenylmethoxy carbonyl chloride (Fmoc-Cl) fluorescent method using an aqueous solution was established to determinate amino groups on nanomaterial surface. The effect factors of determination were investigated and the assay was optimised.... View full abstract»

• Preparation of linoleic acid-capped silver nanoparticles and their antimicrobial effect

Publication Year: 2012, Page(s):81 - 85
| | PDF (368 KB)

Silver nanoparticles have been prepared through the chemical reduction of silver ions by ethanol using linoleic acid as a stabilising agent. This colloidal solution shows an absorption band in the visible range with an absorption peak at 421 nm. The peaks in the X-ray diffraction (XRD) pattern matches well with the standard values of the face-centred-cubic form of metallic silver. Transmission Ele... View full abstract»
