Online monitoring of gold nanoparticles and induced aggregation by photothermal lens microscopy
Autor: Sara Madarshahian, Nader Shokoufi, Atefeh Abbasi-Ahd
Publikováno v: Instrumentation Science & Technology. 46:93-101
In this paper, we have developed inverted photothermal lens microscopy (PTLM) with a flow through optical cell for online detection of gold nanoparticles (AuNPs) to monitor the AuNP production process and aggregation. The indirect detection of the pl

Headspace single-drop microextraction coupled to microchip-photothermal lens microscopy for highly sensitive determination of captopril in human serum and pharmaceuticals
Autor: Kazem Kargosha, Atefeh Abbasi-Ahd, Nader Shokoufi
Publikováno v: Microchimica Acta. 184:2403-2409
The authors describe the combination of headspace single drop microextraction with microchip-photothermal lens microscopy (HS-SDME/MC-PTLM) as a new method for highly sensitive determination of the angiotensin-converting enzyme inhibitor captopril. A

Microfluidic chip-photothermal lens microscopy for DNA hybridization assay using gold nanoparticles
Autor: Atefeh Abbasi-Ahd, Behnaz Abbasgholi Nejad Asbaghi, Nader Shokoufi
Publikováno v: Analytical and bioanalytical chemistry. 411(23)
A new approach employing a microchip in combination with photothermal lens microscopy has been described for a DNA hybridization assay using gold nanoparticles. The difference in adsorption propensities of single- and double-stranded DNAs on gold nan
