Graphene-based electrochemical impedance sensors have recently received much attention due to their outstanding sensing capability and economic viability. In this study, we present a novel means of constructing an impedance sensing platform via harnessing intrinsic π-stacking interactions between probe protein...

The most widely used ionization techniques in liquid chromatography-mass spectrometry (LC-MS) are electrospray ionization (ESI), atmospheric pressure chemical ionization (APCI) and atmospheric pressure photoionization (APPI). All three provide user friendly coupling of LC to MS. Achieving optimal LC-MS conditions is...

Insulin is an approximately 6000 Da peptide hormone used to regulate the glucose concentration in blood. There are several different forms of insulin that are both natural and recombinant; the recombinant forms have been engineered to improve pharmacokinetic properties. A quick and reliable chromatographic technique was developed to identify and detect a mixture of insulin variants in an unknown sample.
