Lanthanide-Based Nanoparticle Synthesis
Synthesis and Characterization of Multifunctional Molecular Assemblies
from bovine pancreas, and methyl viologen were purchased from Sigma-Aldrich.
The disulfides (bis-1-(11-{tetraethylene glycol}-undecyl) disulfide
(EG4C11S)2 and N-{2-(2,5-dioxo-2,5-dihydro-pyrrol-1-yl)-ethyl}-[2-[11-(11-(tetraethylene
glycol)-undecyldisulfanyl)-undecyloxy]-hexaethylene glycol-acetamide])
Mal-EG6C11SSC11EG4) for
SAM preparation were purchased from ProChimia. Alkyl thiol terminated
MV2+ (MV2+-SH) was synthesized as previously
reported.44 (link) NpGGRGDSG (Np-RGD) was synthesized
using an automatic solid-phase synthetic robot (Syro II, Multisyntech)
following standard Fmoc procedures on RinkAmide resin. GGCGGRGDS (C-RGD)
was synthesized with a MultiPep RSi, Intavis Bioanalytical Instruments
using standard solid-phase peptide synthesis protocols on a Wang resin.
Purification was done by reversed-phase high-performance liquid chromatography
(HPLC (Waters)), followed by analysis with analytical HPLC and mass
spectrometry. Because of the poor solubility of CB[8] in water and
its hygroscopic nature, the apparent molecular weight of the commercial
powder and its actual concentration in aqueous solutions were determined
for each batch using a simple and highly reproducible method described
previously.45 (link) CB[8] was dissolved in Milli-Q
water by sonication at 80 °C for 2 h.
Characterization of Fluorescent Probes
5, 6-diamino-naphthalene-1, 3-disulfonic acid (DANDSA) was obtained from Molekula, UK.
4-pyridinium phenolate (4PP) was synthesised and provided by WuXi App Tec (Hong Kong) Ltd. Structure and purity were confirmed by NMR.
The provenances of Brooker's merocyanine (BM), bis-dimethylaminofuchsone (BDF), phenol blue (PB), and 2, 6-dichloro-4-(2, 4, 6-triphenyl-pyridinium-1-yl)-phenolate (ET33) are as stated previously.

Disposable four-sided optically transparent fluorescence cuvettes (Brand GmbH) made of the same material as the UV cuvettes, with stoppers, were used to record fluorescence spectra.
About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
