Introduction

Deoxyribonucleic acid, more commonly known as DNA, stands as the cornerstone of life on Earth. It is a remarkable biomacromolecule that holds the genetic instructions essential for the development, functioning, and evolution of all living organisms. Understanding the structure, function, and significance of DNA is crucial for unraveling the mysteries of life itself. DNA is a macromolecule composed of nucleotides, which are the building blocks of its structure. A DNA molecule consists of two long chains of nucleotides twisted around each other to form a double helix. Each nucleotide is composed of a phosphate group, a sugar molecule (deoxyribose), and one of four nitrogenous bases: Adenine (A), Thymine (T), Cytosine (C), and Guanine (G). The specificity of base pairing adenine with thymine and cytosine with guanine maintains the stability of the DNA double helix.

Discussion

Detection and analysis of cancer-related DNA mutations or aberrations are critical for understanding the molecular basis of cancer and developing targeted therapies. Ultrasensitive DNA technologies facilitate the identification of rare mutations or circulating tumor DNA, enabling early cancer diagnosis and monitoring treatment response. DNA analysis is an essential part of drug development and clinical trials. Ultrasensitive DNA-bio macromolecule technologies can be used to quantify drug target genes, assess the efficacy of treatments, and monitor the presence of drug-resistant mutations. For early detection of disease and cancer, diagnostic testing of biological macromolecules is crucial. However, the interface-based sensing method's sensitive detection of macromolecules remains challenging due to its limited surface area and significant steric hindrance. Introduced here is a "biphasic replacement" electrochemical aptamer-based (BRE-AB) sensing technique that replaces the biomacromolecule's capture reaction with a small diameter of single-stranded DNA to attach to the interface. The ultrasensitive detection of Luteinizing Hormone (LH) with a detection limit of 10 1012 m is demonstrated by means of the BREAB sensor.

The sequence of nucleotides along the DNA strands encodes genetic information. This sequence is transcribed into RNA, which, in turn, guides the synthesis of proteins the molecular machines that perform essential functions in living organisms. The genetic code embedded in DNA is the universal language of life, and the precision of its information storage is awe-inspiring. Before cells divide, DNA undergoes a process called replication to ensure that each daughter cell receives an identical set of genetic information. Enzymes and proteins work together to unwind the double helix, separate the strands, and synthesize new complementary strands. The fidelity of DNA replication is crucial for maintaining the integrity of genetic information through generations. While DNA replication is highly accurate, occasional errors, known as mutations, can occur. Mutations contribute to genetic diversity, driving the evolutionary processes that have shaped life on Earth. Some mutations are harmful, others are neutral, and a few can confer advantages in specific environments. The ability of DNA to undergo mutations and evolve over time is central to the adaptation and survival of species.
