A simple method for the simultaneous, rapid and sensitive determination of N-acylhomoserine lactone signaling molecules in bacterial isolates, without prior sample preconcentration and with minimal sample cleanup, is presented. The analysis relies on the combination of analyte preconcentration and separation on a single device: a relatively large sample volume (1-5 microL) is directly loaded on...

The optical transmission and electric field distribution of plasmonic nanostructures dictate their performance in nano-optics and nano-biosensors. Here, we consider the use of hollow, five-pointed, star-shaped nanostructures made of Al, Ag, Au or Cu. We use simulations based on finite-difference time-domain and the discrete dipole approximation to identify the strongest plasmon resonan‐ ces in ...

This presentation describes three areas of research related to the development of biosensors, nanosensors and biochips for chemical, biological and medical analysis: (1) nanostructured plasmonics-based probes for surface-enhanced Raman scattering (SERS) biochemical analysis, and (2) nanosensors for in vivo analysis of a single cell and (3) multifunctional biochips for medical diagnostics. INTRO...

The nanostructured polyaniline (NSPANI) and its gold nano composite (GNP) with controlled size distribution were developed using structure directing agents (SDA). The nano structure of polyaniline were investigated by UV-Visible spectroscopy, transmission electron microscopy (TEM), dynamic light scattering (DLS), fourrier transform spectroscopy (FTIR), X-ray crystallography and scanning electro...

Nano-scale renewable porous materials have a wide range of applications in the biomedical field such as tissue engineering and biosensors due to their high biocompatibility large surface area. In this study, composite silk fibroin poly(L-lactic acid) was electrospun together form nanofiber biomaterial with 11 blending ratios tune porosity single fibers (19.3–49%). This is highly advantageous ef...

Optical biosensors represent the most common type of biosensor. Here we provide a brief classification, a description of underlying principles of operation and their bioanalytical applications. The main focus is placed on the most widely used optical biosensors which are surface plasmon resonance (SPR)-based biosensors including SPR imaging and localized SPR. In addition, other optical biosenso...
