“…The lead dioxide samples were acid digested using a mixture of 12 mL of HNO 3 and 4 mL of HCl and allowed to boil for 1 h. 31 This dry Pb residue was then dissolved in water and pH balanced to around 6.5. This Pb extract was then filtered for further experimental use.…”

Concurrent developments in anticancer nanotechnological treatments have been observed as the burden of cancer increases every year. The 21st century has seen a transformation in the study of medicine thanks to the advancement in the field of material science and nanomedicine. Improved drug delivery systems with proven efficacy and fewer side effects have been made possible. Nanoformulations with varied functions are being created using lipids, polymers, and inorganic and peptide-based nanomedicines. Therefore, thorough knowledge of these intelligent nanomedicines is crucial for developing very promising drug delivery systems. Polymeric micelles are often simple to make and have high solubilization characteristics; as a result, they seem to be a promising alternative to other nanosystems. Even though recent studies have provided an overview of polymeric micelles, here we included a discussion on the “intelligent” drug delivery from these systems. We also summarized the state-of-the-art and the most recent developments of polymeric micellar systems with respect to cancer treatments. Additionally, we gave significant attention to the clinical translation potential of polymeric micellar systems in the treatment of various cancers.

“…As a result, it′s vital to establish reliable analytical methodologies for measuring their total concentration. Atomic absorption spectroscopy (AAS), [2] ion chromatography (IC), [3] inductively coupled plasma (ICP‐OES), [4] controlled‐potential methods, [5] fluorometric methods, [6,7] and ultraviolet‐visible spectrophotometry (UV‐vis) [1] are the most used techniques. Because of their great selectivity, sensitivity, pricing, accessibility, and low detection limit, spectrophotometric techniques for quantification are gaining significant attention among analytical chemists.…”

A smart spectrophotometric method for the analytical determination of iron concentration in whichever oxidation state was developed using a novel optical sensor. The optical sensor was prepared by direct immobilization of novel synthesized chromophore, 5‐(((1,10‐phenanthrolin‐5‐yl)imino)methyl)‐2‐hydroxybenzoic acid (Phimhb) onto mesoporous silica nanospheres (MSNSs). The novel Phimhb chromophore has two sites, one is selective to Fe(II) ions and the other is selective to Fe(III) ions. The ions′ color can be seen with the human eye and monitored using spectrophotometric techniques or a smartphone. The influence of several parameters on the evaluation of iron ions content was studied and optimized. The proposed method was validated in terms of LOD, LOQ, linearity, and precision according to ICH guidelines. The optical Phimhb sensor has wide linear dynamic ranges with low detection limits of 4.94 ppb (1.83×10−7 mol L−1) and 10.4 ppb (3.85×10−7 mol L−1) for Fe(II) and Fe(III), respectively. The response time of this sensor for both ions was 60 s. The Phimhb sensor could be reproduced multiple times and used with a higher capacity each time. The effect of potential interfering ions on the estimation of Fe(II) and Fe(III) was investigated. The outcomes clarified that the prepared Phimhb sensor was very selective to Fe(II) and Fe(III) ions. Therefore, the Phimhb sensor had been successfully used in the determination of Fe(II) and Fe(III) in real water even without any pre‐concentration, it has high specificity.
