First use of portable system coupling X-ray diffraction and X-ray fluorescence for in-situ analysis of prehistoric rock art
Talanta 129:459 (2014)Study of prehistoric art is playing a major role in the knowledge of human evolution. Many scientific methods are involved in this investigation including chemical analysis of pigments present on artefacts or applied to cave walls. In the past decades, the characterization of coloured mate...
On-line SPE–UHPLC method using fused core columns for extraction and separation of nine illegal dyes in chilli-containing spices
Talanta 130:433 (2014)The presented work describes the development of a simple, fast and effective on-line SPE–UHPLC–UV/vis method using fused core particle columns for extraction, separation and quantitative analysis of the nine illegal dyes, most frequently found in chilli-containing spices. The red dyes Suda...
Electrogenerated chemiluminescence aptasensor for ultrasensitive detection of thrombin incorporating an auxiliary probe
Talanta 130:370 (2014)A novel electrogenerated chemiluminescence (ECL) aptasensor for ultrasensitive detection of thrombin incorporating an auxiliary probe was designed by employing specific anti-thrombin aptamer as a capture probe and a ruthenium(II) complex-tagged reporter probe as an ECL probe and an auxilia...
Stir bar sorptive extraction: Recent applications, limitations and future trends
Talanta 130:388 (2014)Stir bar sorptive extraction (SBSE) has generated growing interest due to its high effectiveness for the extraction of non-polar and medium-polarity compounds from liquid samples or liquid extracts. In particular, in recent years, a large amount of new analytical applications of SBSE has b...
Graphene oxide-based dispersive micro-solid phase extraction for separation and preconcentration of nicotine from biological and environment...
Talanta 130:71 (2014)Graphene oxide (GO) has showed great potential to use as an adsorbent in sample preparation procedures. In this research, GO was used as an effective adsorbent in a simple GO-based dispersive micro-solid phase extraction (GO-D-µ-SPE) method for isolation and preconcentration of nicotine pr...
A nano-patterned self assembled monolayer (SAM) rutile titania cancer chip for rapid, low cost, highly sensitive, direct cancer analysis in ...
Talanta 130:78 (2014)We developed a cancer chip by nano-patterning a highly sensitive SAM titanium surface capable of capturing and sensing concentrations as low as 10 cancer cells/mL from the environment by Matrix Assisted Laser Desorption and Ionization Time of Flight Mass Spectrometry (MALDI-TOF MS). The current appr...
A novel donor–acceptor receptor for selective detection of Pb2+and Fe3+ ions
Talanta 130:103 (2014)An efficient and highly selective colorimetric and fluorescent receptor DTPDA has been synthesized for sensitive detection of Pb2+ and Fe3+ cations. The sensor DTPDA produces a facile, cost-effective and naked eye sensing platform to determine trace amounts of Pb2+ and Fe3+ metal ions by c...

Design of molecularly imprinted polymers for diphenylamine sensing.
A series of the polymers imprinted with diphenylamine (DPA) and respective non imprinted polymers were synthesized using precipitation polymerization. Synthesized polymers were characterized by Fourier Transform Infra-Red spectroscopy with Total Attenuated Reflectance (FTIR-ATR), Sca...
Halogen-free ionic liquid as an additive in zinc(II)-selective electrode: surface analyses as correlated to the membrane activity.
Two conventional Zn(II) polyvinyl chloride (PVC) membrane electrodes have been prepared and characterized. They were based on dibenzo-24-crown-8 (DBC) as a neutral carrier, dioctyl phthalate (DOP) as a plasticizer, and potassium tetrakis (p-chlorophenyl) borate, KTpClPB or the haloge...
