Smartphone fluorescence spectroscopy [PDF]

SPIE Proceedings, 2014
We demonstrate the first use of smartphone spectrophotometry for readout of fluorescence-based biological assays. We evaluated the smartphone fluorimeter in the context of a fluorescent molecular beacon (MB) assay for detection of specific nucleic acid sequences in a liquid test sample and compared performance against a conventional laboratory ...

Preparation, characterization, and nonlinear optical properties of graphene oxide thin film doped with low chirality metallic SWCNTs

Journal of Materials Research and Technology, 2021
We present non-linear optical properties of graphene oxide (GO) doped with low chirality metallic single walled carbon nanotubes (m-SWCNTs) thin films. The weight percentage of the m-SWCNTs was 5, 10, and 20 wt%.

Fluorescence Fluctuation Spectroscopy [PDF]

Methods, 1999
The analysis of the intensity fluctuation of a fluorescence signal from a relatively small volume and from a few molecules contains information about the distribution of different species present in the solution and about kinetic parameters of the system.

Fluorescence correlation spectroscopy and fluorescence cross‐correlation spectroscopy [PDF]

WIREs Systems Biology and Medicine, 2009
AbstractThis article focuses on methods based on fluctuation correlation spectroscopy to determine the formation of protein complexes in living cells. We present the principles of the fluctuation method applied to cells. We discuss the novelty and the promises of this approach. The emphasis is in the discussion of the underlying statistical assumptions

Effect of Ge doping on the material properties of sprayed Cu2SnS3 thin films

Results in Optics, 2023
A facile spray pyrolysis processing of ternary Cu2SnS3 and Cu2Sn1−xGexS3 absorbers is presented. The Cu2SnS3 and Cu2Sn1−xGexS3 thin films were sprayed onto both glass and Mo substrates at 350 °C and then annealed at 550 °C with S and SnS/GeS crystals ...
