Flow injection analysis of pharmaceuticals.

Journal of pharmaceutical and biomedical analysis

Luque de Castro MD, Valcárcel M.
PMID: 2490516
J Pharm Biomed Anal. 1989;7(12):1291-300. doi: 10.1016/0731-7085(89)80135-9.

An overview of the most representative problems solved by flow injection analysis (FIA) in drug analysis is presented. Different aspects of this technique which can be manipulated with specific purposes are discussed and special emphasis is placed on the...

One-Step Synthesis and Characterization of N-Doped Carbon Nanodots for Sensing in Organic Media.

Analytical chemistry

Cayuela A, Carrillo-Carrión C, Soriano ML, Parak WJ, Valcárcel M.
PMID: 26870878
Anal Chem. 2016 Mar 15;88(6):3178-85. doi: 10.1021/acs.analchem.5b04523. Epub 2016 Feb 24.

Photoluminescent nitrogen-doped carbon nanodots (N-doped CNDs) soluble in organic media are synthesized in a one-step synthesis from a single-source precursor (an amphiphilic polymer), which exhibits a very high quantum yield (QY = 78%), excitation wavelength-dependent emission, and upconversion emission...

Neonatal Hyperglycemia due to Transient Neonatal Diabetes Mellitus in Puerto Rico.

Case reports in pediatrics

Fargas-Berríos N, García-Fragoso L, García-García I, Valcárcel M.
