Article Synopsis
  • - This study focuses on improving the methodology for using single particle inductively coupled plasma mass spectrometry (spICP-MS) to analyze biogenic selenium nanoparticles (SeNPs) created by halophilic microorganisms, particularly in hypersaline environments.
  • - The research found that, with the right conditions, spICP-MS can accurately measure SeNPs in high-salt solutions without needing correction factors, and the technique showed low detection limits for both size and concentration.
  • - The results confirmed that the microorganism Haloferax mediterranei can produce SeNPs in the presence of selenite, while selenate does not lead to particle formation, with size and concentration varying based on the experimental conditions.

The overall objective of this work is the evaluation of different competitive aptamer assays based on inductively coupled plasma mass spectrometry (ICP-MS) detection for the determination of β-conglutin (food protein allergen from lupin) in flour samples. To this end, two competitive aptamer assay schemes were developed using either thiolated aptamers chemisorbed onto gold nanoparticles (AuNPs) or biotinylated aptamers linked to streptavidin-AuNPs. The influence of ICP-MS detection mode (i.

Article Synopsis
  • The study investigates the long-term outcomes of patients with metastatic renal cell carcinoma who achieved a complete response to the TKI sunitinib, revealing little known prior information about this group.
  • Data was collected from a registry of 62 patients treated in Spain between 2007 and 2018, with most patients having clear cell histology and previously undergoing nephrectomy.
  • Results show that 75% of patients maintained complete response status after 10 years, indicating durable responses across different prognosis groups and metastasis sites.

Coupling dispersive liquid-liquid micro-extraction (DLLME) to inductively coupled plasma atomic emission spectrometry (ICP-AES) is usually troublesome due to the limited plasma tolerance to the organic solvents usually employed for metal extraction. This work explores different coupling strategies allowing the multi-element determination by ICP-AES of the solutions obtained after DLLME procedures. To this end, three of the most common extractant solvents in DLLME procedures (1-undecanol, 1-butyl-3-methyl-imidazolium hexafluorophosphate and chloroform) have been selected to face most of the main problems reported in DLLME-ICP-AES coupling (i.
