Abstract
Nucleic acids (NAs) are important components of living organisms responsible for the storage and transmission of hereditary information. They form complex structures that can self-assemble and bind to various biological molecules. DNAzymes are NAs capable of performing simple chemical reactions, which makes them potentially useful elements for creating DNA nanomachines with required functions. This review focuses on multicomponent DNA-based nanomachines, in particular on DNAzymes as their main functional elements, as well as on the structure of DNAzyme nanomachines and their application in the diagnostics and treatment of diseases. The article also discusses the advantages and disadvantages of DNAzyme-based nanomachines and prospects for their future applications. The review provides information about new technologies and the possibilities of using NAs in medicine.

Abstract
We have developed a hook-equipped DNA nanomachine (HDNM) for the rapid detection of specific nucleic acid sequences without a preamplification step. HDNM efficiently unwinds RNA structures and improves the detection sensitivity. Compared to the hookless system, HDNM offers an 80-fold and 13-fold enhancement in DNA and RNA detection, respectively, reducing incubation time from 3 to 1 h.
