Green synthesis of peptide-templated fluorescent copper nanoclusters for temperature sensing and cellular imaging

21.10.2014 | Hong Huang; hua Li; Ai-Jun Wang; Shuxian zhong; Keming Fang; Jiu-Ju Feng, Analyst, 2014

A simple and green approach was developed for preparation of fluorescent Cu nanoclusters (NCs) using artificial peptide CLEDNN as a template. The as-synthesized Cu NCs exhibited high fluorescence quantum yield (7.3%) and good stability, along with excitation and temperature dependent fluorescent ...

Manipulating and quantifying temperature-triggered coalescence by microcentrifugation

15.10.2014 | Huanhuan Feng; Dmitry Ershov; Thomas Krebs; K Schroen; Martien A Cohen-Stuart; Jasper van der Gucht; Joris Sprakel, Lab on a Chip, 2014

In this paper we describe a new approach to quantify the stability and coalescence kinetics of thermally switchable emulsions using an imaging-based microcentrifugation method. We first show that combining synchronized high-speed imaging with microfluidic centrifugation allows the direct ...

Application of laser ablation (imaging) inductively coupled plasma mass spectrometry for mapping and quantifying Fe in transgenic and non-transgenic soybean leaves

15.10.2014 | Silvana Ruella Oliveira; Marco Aurélio Zezzi Arruda, Journal of Analytical Atomic Spectrometry, 2014

A laser ablation inductively coupled plasma mass spectrometry is used for determining Fe in leaves of transgenic (variety M 7211RR) and non-transgenic (variety MSOY 8200) soybean, grown for 21 days in a growth chamber at controlled temperature (27 ± 0.1 oC) and photoperiod (12 h). The same ...
