Highly selective and sensitive recognition of multi-ions in aqueous solution based on polymer-grafted nanoparticle as visual colorimetric sensor
Characterization of the chemosensor The XRD analysis X-ray diffraction technique is typically used to investigate and identify phase formation and obtain information about the crystallinity of the TiO2 NPs and poly(AM-MBA-DTZ)-grafted TiO2 NPs. The obtained X-ray diffraction patterns for TiO2 NPs and polymeric matrices are shown in Fig. 2. The diffraction patterns and peak positions of TiO2…

Introducing a portable electrochemical biosensor for Mycobacterium avium subsp. paratuberculosis detection using graphene oxide and chitosan
Characterization of graphene oxide nanoparticles (GO) Initially, the as-prepared graphene oxide nanoparticles were characterized by imaging method using Scanning Electron Microscopy (SEM) (TESCAN-Vega3 Brno, Czech Republic). In this regard, the SEM image of the as-prepared graphene oxide nanoparticles was recorded (Figure s1). The results revealed that the prepared graphene oxide nanoparticles have a size distribution…

A light-activatable theranostic combination for ratiometric hypoxia imaging and oxygen-deprived drug activity enhancement
Synthesis and properties of the NIR-emitting ratiometric phosphorescence probe Ir-tetraphenylbenzoporphyrin (IrTBP), an oxygen-sensitive phosphorescent complex, was initially synthesised (Supplementary Fig. 1), and the structure was confirmed by 1HNMR and MALDI-TOF-MS spectra (Supplementary Figs. 2 and 3). Ir containing nanoprobes, Ir-NP, were then prepared by self-assembly of chlorosulfonylated IrTBP, chlorosulfonylated tetraphenylporphyrin (TPP) and α, ω-amino-terminated polyethylene glycol in…
