Paper
Synthesis and characterization of a rhodamine derivative as a selective switch-on fluorescent sensor for Cu2+ ions in aqueous PBS buffer and living cells
A novel rhodamine-based receptor molecule (L1) was synthesized via the reaction between rhodamine hydrazide and acetylacetone.
Paper
Development of fluorometric detection for saxitoxin with its specific binding peptide
A fluorometric sensor for marine saxitoxin was developed using its specific binding peptide based on the graphene oxide-mediated quenching phenomenon.
Paper
From the lab to the field: handheld surface enhanced Raman spectroscopy (SERS) detection of viral proteins
This work employs peptide-modified gold nanoparticles to develop a fieldable SERS sensor for direct detection of viral antigens using a handheld platform.
Paper
A selective chemosensor via click chemistry for Cu2+ and Hg2+ ions in organic media
A simple chemosensor, 4-amino antipyrine linked bis-1,2,3-triazole, was synthesized via the “click” approach using the CuAAC method and characterized by FTIR, NMR, and ESI-MS spectroscopy, for the selective detection of Hg(II) and Cu(II) ions.
About this collection
We are pleased to present this themed collection Guest Edited by Prof. Suresh Kumar Kailasa (Sardar Vallabhbhai National Institute of Technology, India), Prof. Tae Jung Park (Chung-Ang University, South Korea), and Prof. Tsuyoshi Minami (The University of Tokyo, Japan).
This themed collection brings together cutting-edge research on the modification of various nanostructured materials with different ligand chemistries to develop plasmonic, fluorescence and electrochemical sensors for molecular diagnostics, and focuses on providing insights into nanostructure modification to improve selectivity and sensitivity for translating diagnostic tools from the lab to point-of-care diagnostics.
