1. Targeted drug delivery is made possible by nanotechnology.
2. Nanotechnology can largely contribute to gene therapy.
Select the correct answer using the codes given below.
Explanation
: Nanotechnology is a field of science and engineering that deals with the manipulation of matter on an atomic and molecular scale, typically between 1 to 100 nanometers. It involves the design, synthesis, characterization, and application of materials, devices, and systems at this incredibly small scale. This emerging field has the potential to revolutionize various sectors, including medicine, electronics, materials science, and energy, by creating new materials with unique properties and developing innovative technologies with unprecedented capabilities.
Statement 1 is correct: Targeted drug distribution by nanoscale drug carriers is one of the fundamental tenets of nanomedicine. Numerous nanoscale drug delivery technologies, such as liposomes, dendrimers, quantum dots, nanotubes, polymeric biodegradable nanoparticles, and nanocapsules, have been studied.
Statement 2 is correct: Nanotechnology plays a significant role in gene therapy by creating nanocarriers that can deliver genetic material, such as DNA or RNA, to specific cells. These nanocarriers protect genetic material from degradation and improve its delivery into target cells, offering potential treatments for genetic disorders.
