Rapid detection of SARS-CoV-2 infection by multicapillary column coupled ion mobility spectrometry (MCC-IMS) of breath. A proof of concept study

medRxiv, 2020
There is an urgent need for screening of patients with a communicable viral disease to cut infection chains. Recently, we demonstrated that ion mobility spectrometry coupled with a multicapillary column (MCC-IMS) is able to identify influenza-A ...

Development and Application of an Ion Gate Driving Power Supply for Inverse Ion Mobility Spectrometry

Zhipu Xuebao
Ion mobility spectrometry (IMS) is a trace detection technique. It realizes rapid separation and detection of ions by capitalizing on the disparities in the mobility velocities of ions in an electric field under atmospheric pressure.

Characterization of Amyloid Oligomers by Electrospray Ionization-Ion Mobility Spectrometry-Mass Spectrometry (ESI-IMS-MS) [PDF]

, 2016
Soluble oligomers formed during the self-assembly of amyloidogenic peptide and protein species are generally thought to be highly toxic. Consequently, thorough characterization of these species is of much interest in the quest for effective therapeutics and for an enhanced understanding of amyloid fibrillation pathways.

Ligand Engineering for Precise Control of Ultrathin CsPbI3 Nanoplatelet Superlattices for Efficient Light‐Emitting Diodes

Advanced Materials, EarlyView.
In this work, we introduce ancillary‐ligand‐mediated growth control of ultrathin CsPbI3 PeNPLs to achieve highly uniform thickness and reduced agglomeration. Strong ancillary‐ligand coordination to the perovskite surface regulates nucleation and improves surface passivation, enabling color‐pure emission and preferentially oriented superlattices.

Rational Design of π‐Conjugated Polymers for Enantioselective Recognition of Amino Acids

Advanced Electronic Materials, EarlyView.
A family of conducting polymers is proposed for the enantioselective recognition of amino acids. The films are generated by electropolymerization of thiophene trimers containing chiral features, with the advantage that the polymerization can be induced at much lower overpotentials compared to classic thiophene monomers, thus avoiding parasitic ...
