“…[41] However, these photophysical properties of the dye get significantly modulated upon binding to the supramolecules or biomolecules. These are accompanied by variations of their excited-state electron transfer properties, [42,43] which are also relevant for their use as drugs in photodynamic therapy and as antimicrobial agents. [44][45][46] In addition, TPM dyes are used as aptamer-based fluorescence sensors to assay the formation, location, or breakdown of RNA.…”

Construction and characterization of stimuli‐responsive supra‐biomolecular nanoassembly between cucurbit[7]uril (CB7) and bovine serum albumin (BSA), uptake and release of doxorubicin (DOX) in live cells, the enhanced sensitivity of brilliant green (BG) and the metal ion‐induced relocation of neutral red (NR) dye to BSA have been discussed in this review. The fluorescence intensity of DOX is largely quenched in the presence of nanoassembly which recovers with adamantylamine or by changing the pH of the solution, indicating the significant uptake and release of DOX. Whereas, the interaction of BG with CB7‐BSA assembly leads to a huge fluorescence enhancement ∼350‐fold through ternary complex formation. In another study, the supramolecular pKa tuning of nanoassembly encapsulated NR dye with metal ion and the consequent relocation of NR from CB7 cavity to the hydrophobic pocket of BSA have been demonstrated. All these studies show promising applications in drug delivery and on‐off sensor.

“…This could be attributed to the decomposition of malachite green in the presence of the oxidizing agent. [ 52 ] In Figure S4 (Supporting Information), the decomposition of malachite green in water, measured by UV/vis spectroscopy, is presented in dependence on time and concentration of iron(III) chloride. This phenomenon could also be observed by increasing the iron(III)chloride concentration for both samples, the PMMA and the PFcMA capsules, in the release experiments as depicted in Figure S5 (Supporting Information).…”

A convenient synthetic approach for the preparation of uniform metallopolymer-containing hollow spheres based on 2-(methacryloyloxy)ethyl ferrocenecarboxylate (FcMA) as monomer by sequential starved feed emulsion polymerization is described. Core/shell particles consisting of a noncrosslinked poly(methyl methacrylate) core and a slightly crosslinked ferrocene-containing shell allows for the simple dissolution of core material and, thus, monodisperse metallopolymer hollow spheres are obtained. Since PFcMA is incorporated in the particle shell, herein investigated hollow spheres can be addressed by external triggers, i.e., solvent variation and redox chemistry in order to change the particle swelling capability. PFcMA-containing core/shell particles and hollow spheres are characterized by transmission electron microscope (TEM), scanning electron microscopy, cryogenic TEM, thermogravimetric analysis, and dynamic light scattering in terms of size, size distribution, hollow sphere character, redox-responsiveness, and composition. Moreover, the general suitability of prepared stimulus-responsive nanocapsules for the use in catch-release systems is demonstrated by loading the nanocapsules with malachite green as model payload followed by release studies.

“…MV, known also as crystal violet (molecular formula -C 25 H 30 CIN 3 , molecular mass -408 Da), is a triphenylmethane dye (Fig. 1), being used as a biological stain, fungicide in the agriculture, exterior drug for skin diseases [24,25]. It also possesses good sterilization, little toxicity and hormesis [26].…”

In this work the study of the effect of millimeter range electromagnetic waves (MM EMW) on methyl violet interaction with human serum albumin (HSA) has been carried out, using the UV-denaturation, fluorescence spectroscopy and CD spectroscopy methods. It was revealed that MM EMW irradiation leads to weakening of the stability of HSA and decreasing of interaction force between HSA and methyl violet (MV). It was also shown that MM EMW irradiation by water non-resonant frequency, affecting immediately the structure of HSA, changes its secondary structure, while the irradiation by water-resonant frequency does not invoke structural changes, but weakens the stability more. The last insistence results from the water cluster reconstruction, due to which the structured water affects the conformation of HSA.
