Diffuse Optics (2010-08-30)

Author(s): Turgut Durduran

This review describes the diffusion model for light transport in tissues and the medical applications of diffuse light. Diffuse optics is particularly useful for measurement of tissue hemodynamics, wherein quantitative assessment of oxy- and deoxy-hemoglobin concentrations and blood flow are desired.

Fast and Efficient Detection of Pathogens Using Raman Spectroscopy and Chip-Based Methods (2010-08-30)

Author(s): Robert Möller, Petra Rösch, Jürgen  Popp

The detection and identification of microorganisms is not only of high relevance for a variety of medical applications, rather it has become an important analytical task in many fields like food production, environmental applications, biotechnology and many more. By identifying microorganisms, disease causing agents or microbial contaminations in food or environmental samples can be confirmed.

Surface enhanced Raman spectroscopy (SERS) – a powerful tool in analytical, bioanalytical and biomedical diagnostics (2010-08-30)

Author(s): Dana Cialla, Anne März, Katharina Strelau, Robert Möller, Jürgen  Popp

Raman signals are inherently weak and therefore usually do not allow the investigation of substances at a low concentration level, e. g. residues of medics in body liquids. A solution to this problem is surface-enhanced Raman spectroscopy (SERS).

Optical Tweezers: Novel Photonics for the Life Sciences (2010-08-30)

Author(s): David Stevenson, Tomás Cizmár, Kishan  Dholakia

Whilst visually evocative and powerful just moving or trapping objects is insuffi cient. The success of optical tweezers has been its ability to be a calibrated force transducer: the particle is trapped in a harmonic potential well and the force of the particle is proportional to displacement (rather like a microscopic version of a Hookean spring).

Laser fabrication of 3D scaffolds for tissue engineering (2011-05-06)

Author(s): Maria Farsari

Tissue Engineering is defined as the technology aiming to ‘apply the principles of engineering and life sciences towards the development of biological substitutes that restore, maintain, or improve tissue function or a whole organ’1. One of its research aims is, therefore, to create materials that are biocompatible and capable of integrating living cells. This usually involves three steps: (i) identifying a material suitable for the fabrication of a scaffold for a specific tissue engineering application, (ii) structuring of the scaffold material and (iii) cell seeding into the scaffold for cell culturing in vitro or in vivo.

Round Robin Experiment

Raman spectroscopy has already proved its effectiveness in many cases for medical diagnostics such as for cancer, cardiovascular diseases and infections. However, there are no standards in the different working groups, e.g. for sample preparation, implementation of the Raman experiments, spectra pre-treatment, data evaluation, etc.In a round robin experiment, the required groundwork will take place in order to define standardised Raman measurement methods, which will be fundamental for establishing Raman spectroscopy for clinical diagnostic procedures.

5th International Conference on Biophotonics

20 March 2017

Continuing the success of the previous meetings held in Sacramento, Ottawa, Jena, and Florence, the 5th conference will come to Perth, Western Australia, running over two full days, and back-to-back with the Science on the Swan medical research conference, which delegates are strongly encouraged to also attend, at discounted rates. [more]
