Material Limitations on the Detection Limit in Refractometry [PDF]

Sensors, 2009
We discuss the detection limit for refractometric sensors relying on high-Q optical cavities and show that the ultimate classical detection limit is given by min {Δn} ≳ η with n + iη being the complex refractive index of the material under refractometric investigation.

Molecularly Imprinted Electrochemical Sensor-Based Fe2O3@MWCNTs for Ivabradine Drug Determination in Pharmaceutical Formulation, Serum, and Urine Samples

Frontiers in Bioengineering and Biotechnology, 2021
Ivabradine hydrochloride (IVR) is a medically important drug because of its ability to lower the heart rate. Techniques reported for IVR determination were expensive, laborious, besides being of poor selectivity.

Measurements below the detection limit.

Tidsskrift for Den Norske Laegeforening, 2022
Let's start with an example: Figure 1 shows a fictional dataset of measurements of serum levels of a substance in two patient groups. The crosses indicate the actual values, but only those above the lower detection limit can be measured. We know how many

In-vitro Study for Cerenkov Luminescence Imaging Application in Hepatic Metastasectomy

Frontiers in Physics, 2021
Cerenkov luminescence imaging (CLI) has been recently proposed as a method to visualize surgical margins in the operating theater, immediately after resection, to allow refining surgery in a single procedure. Our group is preparing a pilot clinical study

Fundamental Limitation on the Detectability of Entanglement

Physical Review Letters, 2022
Entanglement detection is essential in quantum information science and quantum many-body physics. It has been proved that entanglement exists almost surely for a random quantum state, while the realizations of effective entanglement criteria usually consume exponential resources, and efficient criteria often perform poorly without prior knowledge. This
