A bio-mimicking cobalt tetramenthol-substituted phthalocyanine-based electrochemical sensor for selective and sensitive detection of -butylhydroquinone.

Healthy eating choices and adequate nutritional foods are the most important factors in extending a person's life expectancy. Synthetic antioxidants are frequently used in the food industry as preservatives despite their toxicity and hence have drawn much attention for their accurate monitoring. This study explores the newly designed cobalt tetramenthol substituted phthalocyanine (CoTMPc) for the electrocatalytic detection of an artificial food preservative, , tertiary butylhydroquinone (TBHQ).

Tracking KP.2 SARS-CoV-2 Variant in India and the Clinical Profile of KP.2 Cases in Maharashtra, India.

Background:  Following the emergence of the JN.1 SARS-CoV-2 variant, variants with key mutations in the spike protein, such as L455F, F456L, and R346T, were identified. In early January 2024, the KP.

Emerging Role of Injectable Dipeptide Hydrogels in Biomedical Applications.

Owing to their properties such as biocompatibility, tunable mechanical properties, permeability toward oxygen, nutrients, and the ability to hold a significant amount of water, hydrogels have wide applications in biomedical research. They have been engaged in drug delivery systems, 3D cell culture, imaging, and extracellular matrix (ECM) mimetics. Injectable hydrogels represent a major subset of hydrogels possessing advantages of site-specific conformation with minimal invasive techniques.

A comparative study of structural, acidic and hydrophilic properties of Sn-BEA with Ti-BEA using periodic density functional theory.

Periodic density functional theory has been employed to characterize the differences in the structural, Lewis acidic and hydrophilic properties of Sn-BEA and Ti-BEA. We show that the incorporation of Sn increases the Lewis acidity of BEA compared to the incorporation of Ti. Hence, the present work gives insight into the role of Sn in increasing the efficiency of the oxidation reactions.
