Abstract

Recently, the multidisciplinary field of nanotechnology has garnered significant interest due to its diverse applications. Among the contemporary branches of nanotechnology, DNA nanobiotechnology has emerged as a captivating area of study, combining the principles of nanotechnology with oligonucleotides. This innovative science employs a variety of nucleotide structures, including aptamers, siRNAs, antisense oligonucleotides, and others. In this investigation, we conducted a comprehensive review of the hazards and challenges associated with DNA nanobiotechnology. Despite the numerous advantages of DNA and RNA oligonucleotides, their utilization may elicit adverse effects in plants and animals. Our literature review revealed that these oligonucleotides can trigger a range of detrimental reactions, such as intense immune system stimulation, induction of cell death, pro-inflammatory responses, vascular damage, kidney damage, anticoagulant effects, inhibition of bone marrow hematopoiesis, prevention of protein synthesis, alteration of gene expression, allergic reactions, leukopenia, hyperplasia, tissue accumulation, development of new toxins and allergens, emergence of antibiotic-resistant strains, and challenges pertinent to the food industry. Given the findings of our review, it is crucial for researchers to not only focus on the positive aspects of DNA nanobiotechnology but also to consider the potential negative consequences of this scientific domain. © The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature 2024.
