چکیده
LNA, which stands for low noise amplifier, as the name suggests, is used for amplifying weak and very low power signals. LNA is an important part of transceiver system. It is the fundamental building block of communication systems. LNA is used in industrial, scientific and medical bands (ISM). Radios, cellular telephones, GPS receiver, and satellite communication, etc. employ LNA. In this paper, we have discussed about various topologies of LNA and their mode of implementation in biomedical applications. Biomedical applications involve the use of LNA in neural applications, biosensors, ECG applications, etc. Comparison of the different topologies in terms of power consumption, chip area and mode of implementation has

متن کاملNano-graphene oxide as a novel platform for monitoring the effect of LNA modification on nucleic acid interactions.
Graphene oxide has gained significant attention due to its exceptional physical properties at biological interfaces. It has extraordinary quenching, fast adsorption and desorption properties that are suitable for detection of molecular interactions in nucleic acids. Here we studied the interaction between locked nucleic acid (LNA) modified oligonucleotides and its complementary miR-10b DNA anal...
متن کاملInvader LNA: efficient targeting of short double stranded DNA.
Despite progress with triplex-forming oligonucleotides or helix-invading peptide nucleic acids (PNAs), there remains a need for probes facilitating sequence-unrestricted targeting of double stranded DNA (dsDNA) at physiologically relevant conditions. Invader LNA probes, i.e., DNA duplexes with "+1 interstrand zipper arrangements" of intercalator-functionalized 2'-amino-alpha-l-LNA monomers, are...
