    Nanotechnology in leukemia: diagnosis, efcient-targeted drug delivery, and clinical trials
    (BioMed Central Ltd, 2023-11) Salama, Maha M; Aborehab, Nora M; El Mahdy, Nihal M; Zayed, Ahmed; Ezzat, Shahira M
    Leukemia is a group of malignant disorders which afect the blood and blood-forming tissues in the bone marrow, lymphatic system, and spleen. Many types of leukemia exist; thus, their diagnosis and treatment are somewhat complicated. The use of conventional strategies for treatment such as chemotherapy and radiotherapy may develop many side efects and toxicity. Hence, modern research is concerned with the development of specifc nano-formulations for targeted delivery of anti-leukemic drugs avoiding toxic efects on normal cells. Nanostructures can be applied not only in treatment but also in diagnosis. In this article, types of leukemia, its causes, diagnosis as well as conventional treatment of leukemia shall be reviewed. Then, the use of nanoparticles in diagnosis of leukemia and synthesis of nanocarriers for efcient delivery of anti-leukemia drugs being investigated in in vivo and clinical studies. Therefore, it may contribute to the discovery of novel and emerging nanoparticles for targeted treatment of leukemia with less side efects and toxicities.

    Toxicity of Nanoparticles in Biomedical Application: Nanotoxicology
    (Hindawi, 7/30/2021) Egbuna, Chukwuebuka; Parmar, Vijaykumar K.; Jeevanandam, Jaison; Ezzat, Shahira M; Patrick-Iwuanyanwu, Kingsley C; Adetunji, Charles Oluwaseun; Khan, Johra; Onyeike, Eugene N; Uche, Chukwuemelie Zedech; Akram, Muhammad; Ibrahim, Mervat S; El Mahdy, Nihal M; Awuchi, Chinaza Godswill; Saravanan, Kaliyaperumal; Tijjani, Habibu; Odoh, Uchenna Estella; Messaoudi, Mohammed; Ifemeje, Jonathan C; Olisah, Michael C; Ezeofor, Nebechi Jane; Chikwendu, Chukwudi Jude; Ibeabuchi, Chinwe Gloria
    Nanoparticles are of great importance in development and research because of their application in industries and biomedicine. )e development of nanoparticles requires proper knowledge of their fabrication, interaction, release, distribution, target, compatibility, and functions. )is review presents a comprehensive update on nanoparticles’ toxic effects, the factors underlying their toxicity, and the mechanisms by which toxicity is induced. Recent studies have found that nanoparticles may cause serious health effects when exposed to the body through ingestion, inhalation, and skin contact without caution. )e extent to which toxicity is induced depends on some properties, including the nature and size of the nanoparticle, the surface area, shape, aspect ratio, surface coating, crystallinity, dissolution, and agglomeration. In all, the general mechanisms by which it causes toxicity lie on its capability to initiate the formation of reactive species, cytotoxicity, genotoxicity, and neurotoxicity, among others.
