Disease Fighting Machines Inside the Body: A Review

Abstract

Nanotechnology will bring about a revolution in the globe. The National Nanotechnology Initiative (NNI) defines nanotechnology as the study of all particles with a dimension of 100 nanometers or less. One of the main advantages of smaller particles is the rise in the ratio of surface atoms or molecules to total number. Due to their large surface area, which enhances surface activity and alters their biological and physical features, they have many surfaces. Drugs having nanoscalesized active ingredients are referred to as nanotechnology applications in the pharmaceutical sector. They can repair damaged tissue at the cellular level, are helpful in detecting, diagnosing, and treating illness, and are beneficial in treating severe diseases like HIV, cancer, and others. Drugs can now be injected into previously inaccessible areas of the body thanks to smaller drug delivery systems, which are also essential for the treatment and early diagnosis of specific diseases like cancer. Target treatment, a recent development in pharmaceutical administration, improves medical equipment and diagnostic techniques.
