Biological samples are complex and often contain many proteins, lipids and other
contaminants, which affect the separation and ionization properties of the analytes …

Solid phase extraction (SPE) and solid phase microextraction (SPME) are among the most
significant sample clean-up and pretreatment techniques, which have attracted a …

Polycyclic aromatic hydrocarbons (PAHs), as an important class of pollutants, are persistent
in the environment and have adverse effects on human health, including carcinogenicity and …

The determination of organic and inorganic analytes from biological samples need efficient
sample preparation procedures in order to capture the analyte in a media with many …

New advanced materials' potential as sorbents during the sample preparation process has
recently been highlighted by developments in contemporary analytical chemistry …

We proposed a facile DNA-based hydrogel capillary sensor (DHCS) for sensitive detection
of Pb 2+. This proposed biosensor took advantage of the capillary action of the capillary tube …

Magnetic restricted-access carbon nanotubes (M-RACNTs) were synthesised and used for
dispersive solid phase extraction of organophosphates (chlorpyriphos, malathion, disulfoton …

The restricted access molecularly imprinted polymers (RAMIPs) were applied in food and
biological analysis in order to faster and more effective determine the target molecules …

Signal amplification provides an effective way to improve detection performance. Herein, an
ultrasensitive electrochemiluminescence (ECL) aptasensor for Pb 2+ detection was …

Abstract Lead ion (Pb 2+) is a common environmental contaminant, which causes serious
bioaccumulation and toxicity in human body. In this work, we developed a novel Pb 2+ …
