Illicit Drug‐Derived Volatile Organic Compounds as Markers for Application in Noncontact Detection Technology

open access: yesThe Chemical Record, EarlyView.
This review highlights the characteristic odor markers of illicit drugs, emphasizing volatile markers from both natural and synthetic sources, and explores the shift from canine‐based detection to emerging noncontact sensing technologies. Illicit drug use remains a global concern, requiring effective detection methods to counter evolving concealment ...

Advances in cholesterol and lipoproteins detection for healthcare: A review

open access: yesVIEW, EarlyView.
Cholesterol is one of the main biomarkers related to the development of cardiovascular diseases. Its detection still relies on traditional methods of analysis, such as gas and liquid chromatographies. Detection of free cholesterol in saliva with redox or enzymatic sensors or detection of lipoproteins in blood with aptamer sensors are currently the most

Gas check prevention during calendering of poly(vinyl chloride) films using poly(caprolactone)‐based additives

open access: yesJournal of Vinyl and Additive Technology, Volume 31, Issue 2, Page 441-452, March 2025.
Three poly(caprolactone) (PCL)‐based additives of differing molecular weights were used as a secondary plasticizer to prevent gas checks in PVC films produced through calendering. Results showed that chemical and physicochemical properties influence the prevention or reduction of gas checks, unlike rheological properties including complex viscosity and

Molecular imprinting

Analytical and Bioanalytical Chemistry, 2007
Our senses of smell and taste are able to recognise molecules selectively, to the point where they can even discriminate between different chiral states. This property, called molecular recognition, is essential to all forms of life [1]. It is based on the principle of a specific interaction between a receptor or host and a target molecule, which will ...

Molecular imprinting

Trends in Biochemical Sciences, 1994
Molecular imprinting is an emerging methodology for the creation of selective recognition sites in synthetic polymers. This technique entails the polymerization of functional monomers in the presence of an important molecule (template). Recent studies have shown that the polymers obtained exhibit a surprisingly high degree of stereo- and regiospecific ...

Molecular imprinting of surfaces

Bioseparation, 2001
Recent years have seen the development of a number of novel strategies for improving the performance of molecularly imprinted polymers and for adapting them to new application areas. The imprinting of surfaces has received significant attention over the past few years, due to the possibilities available in terms of the imprinting of macromolecular ...

Molecular Imprinting Made Easy

Journal of the American Chemical Society, 2004
A simple method of molecular imprinting is presented that uses a single cross-linking monomer N,O-bismethacryloyl ethanolamine (NOBE) along with template, initiator, and solvent. This formulation eliminates the need for additional functional monomers and empirical optimization of relative ratios of functional monomers, cross-linkers, and template.
