Application

Selected application examples
Calcium ionophore II (ETH 129) was used in preparing calcium selective minielectrodes which are used in determination of dissociation constant (Kd).
Suitable for intracellular calcium measurements.
Lipophilic ionophore for Ca2+-selective electrodes with detection limit in the sub-nanomolar range. Extremely efficient carrier of Ca2+-ions; induces a selectivity in membranes for Ca2+ over Mg2+ by a factor of about 104.

Packaging

Bottomless glass bottle. Contents are inside inserted fused cone.

Wearable health monitoring has garnered considerable interest from the healthcare industry as an evolutionary alternative to standard practices with the ability to provide rapid, off-site diagnosis and patient-monitoring. In particular, sweat-based wearable biosensors offer a noninvasive route to continuously monitor

Ultrathin metallic WS2 (M-WS2) nanosheets and semiconductive WS2 (S-WS2) nanosheets were exfoliated and for the first time employed as ion-to-electron transducing layer to construct an all-solid-state ion-selective electrode. Importantly, we found that the transducing efficiency of WS2 nanosheet-based solid-contact layer is
