Despite a large number of studies undertaken, limited selectivity and efficacy of TiO2 photocatalyst are still widely accepted problems.
Although the currently available inhibitors have limited selectivity and moderate potency, they can function as research tools and as starting point for the development of activity-based probes, which are reagents that can specifically detect active rhomboid species.
Binding of phospholipids to the annular sites on KcsA shows limited selectivity with, for example, a binding constant for phosphatidic acid relative to DOPC of ∼2.0.
While a handful of leads have been discovered with potencies in the nanomolar range, there is typically limited selectivity over the human homologue, and host cell toxicity effects are variable.
In addition, since the ATP-binding site is highly conserved in RTKs, most inhibitors exhibit limited selectivity within RTKs, which induces side effects during treatment, such as nausea, weakness, and elevated blood pressure [ 25].
Their major drawbacks remain the poor overall properties regarding metabolic stability, oral bioavailability, membrane permeability and conformational stability, limiting their selectivity with the target.
This indicates that isoalkanes are, at least for the longer alkanes, more active than the n-alkanes themselves and undergo rapid conversion, thereby severely limiting the selectivity to isomers that can be obtained at high conversions.
These include the slope, long- and short-term stability and reproducibility of potential, detection limits, selectivity coefficients, response time and life-time of the microelectrodes.
The structure and properties such as low detection limit, selectivity and miniaturized size enables potential application of this device in wearable transdermal alcohol measurements.
These criteria are recommended for authors, referees and educators and include calibration characteristics (sensitivity, operational and linear concentration range, detection and quantitative determination limits), selectivity, steady-state and transient response times, sample throughput, reproducibility, stability and lifetime.
