A computational study for the B 30 bowl-like nanostructure as a possible candidate for drug delivery system for amantadine

Potential of B24O24 nanocluster for sensing and delivering chlormethine anticancer drug: a DFT study

In the present research, the adsorption and release of chlormethine (CM) drug on the B₂₄O₂₄ nanocage have been reported in the water media and gas phase at GGA/PBE/DNP computational level. The interaction between B₂₄O₂₄ nanocage and CM drug shows that adsorptions of the chlormethine on B₂₄O₂₄ nanocage for the most stable complexes are - 1.47 to - 1.36 eV in the gas phase and water media, respectively. The CM adsorption caused a notable change in the band gap (E_g) and work function (Φ) of the B₂₄O₂₄ nanocage in the studied complexes. The binding of chlormethine to B₂₄O₂₄ also significantly increased the polarity of the drug carrier, which is a desirable property for drug delivery in biological environments. CM drugs can be released from the nanocage in the presence of an external electric field along the X-axis direction. The present study results show that the B₂₄O₂₄ nanocage is a possible carrier for delivering chlormethine drugs.

The recent advancement of low-dimensional nanostructured materials for drug delivery and drug sensing application: A brief review

In this review article, we have presented a detailed analysis of the recent advancement of quantum mechanical calculations in the applications of the low-dimensional nanomaterials (LDNs) into biomedical fields like biosensors and drug delivery systems development. Biosensors play an essential role for many communities, e.g. law enforcing agencies to sense illicit drugs, medical communities to remove overdosed medications from the human and animal body etc. Besides, drug delivery systems are theoretically being proposed for many years and experimentally found to deliver the drug to the targeted sites by reducing the harmful side effects significantly. In current COVID-19 pandemic, biosensors can play significant roles, e.g. to remove experimental drugs during the human trials if they show any unwanted adverse effect etc. where the drug delivery systems can be potentially applied to reduce the side effects. But before proceeding to these noble and expensive translational research works, advanced theoretical calculations can provide the possible outcomes with considerable accuracy. Hence in this review article, we have analyzed how theoretical calculations can be used to investigate LDNs as potential biosensor devices or drug delivery systems. We have also made a very brief discussion on the properties of biosensors or drug delivery systems which should be investigated for the biomedical applications and how to calculate them theoretically. Finally, we have made a detailed analysis of a large number of recently published research works where theoretical calculations were used to propose different LDNs for bio-sensing and drug delivery applications.
