Current Trends in Nanotechnology-based Drug Delivery Systems for the Diagnosis and Treatment of Malaria: A Review.

Malaria is still a major endemic disease transmitted in humans via Plasmodium-infected mosquitoes. The eradication of malarial parasites and the control measures have been rigorously and extensively deployed by local and international health organizations. Malaria's recurrence is a result of the failure to entirely eradicate it. The drawbacks related to malarial chemotherapy, non-specific targeting, multiple drug resistance, requirement of high doses, intolerable toxicity, indefinable complexity of Plasmodium's life cycle, and advent of drug-resistant strains of P. falciparum are the causes of the ineffective eradication measures. With the emergence of nanotechnology and its application in various industrial domains, the rising interest in the medical field, especially in epidemiology, has skyrocketed. The applications of nanosized carriers have sparked special attention, aiming towards minimizing the overall side effects caused due to drug therapy and avoiding bioavailability. The applications of concepts of nanobiotechnology to both vector control and patient therapy can also be one of the approaches. The current study focuses on the use of hybrid drugs as next-generation antimalarial drugs because they involve fewer drug adverse effects. The paper encompasses the numerous nanosized delivery-based systems that have been found to be effective among higher animal models, especially in treating malarial prophylaxis. This paper delivers a detailed review of diagnostic techniques, various nanotechnology approaches, the application of nanocarriers, and the underlying mechanisms for the management of malaria, thereby providing insights and the direction in which the current trends are imparted from the innovative and technological perspective.
