DNA nanotechnology is a unique field, where physics, chemistry, biology, mathematics, engineering, and materials science can elegantly converge. Since the original proposal of Nadrian Seeman, significant advances have been achieved in past four decades. During this glory time, origami technique developed by Paul Rothemund further pushed field forward with vigorous momentum, fostering plethora concepts, models, methodologies, applications that were not thought before. This review focuses on recent progress origami-engineered nanomaterials five years, outlining exciting achievements as well unexplored research avenues. We believe spirit assets Seeman left for scientists will continue to bring interdisciplinary innovations useful next decade.

These days, cancer is thought to be more than just one illness, with several complex subtypes that require different screening approaches. can distinguished by the distinct markings left metabolites, proteins, miRNA, and DNA. Personalized illness management may possible if categorized according its biomarkers. In order stop from spreading posing a significant risk patient survival, early detection prompt treatment are essential. Traditional techniques tedious, time-consuming, expert personnel for analysis. This has led scientists reevaluate methodologies make use of emerging technologies achieve better results. Using time money saving techniques, these integrate procedures sample preparation in small devices high accuracy sensitivity. With proven potential biomedical use, surface-enhanced Raman scattering (SERS) been widely used biosensing applications, particularly biomarker identification. Consideration was given especially SERS as portable clinical diagnostic tool. The approaches SERS-based sensing both invasive non-invasive samples reviewed this article, along obstacles. Aside constraints approach review also takes into account complexity biological fluids, availability biomarkers, their sensitivity selectivity, which generally lowered. Massive ways maintain capabilities being developed recently get over restriction. known reliable method judgments. Nonetheless, there still room advancement terms portability, creation apps, interdisciplinary AI-based applications. Therefore, we will outline current state technological maturity article. meet demand reviewing various types (invasive non-invasive) biomarkers using SERS. It shed light on growing body research methods application quick detection.

Over the past decade, DNA nanotechnology has spawned a broad variety of functional nanostructures tailored toward enabled state at which applications are coming increasingly in view. One branches these is synthetic biology, where intrinsic programmability may pave way for smart task-specific molecular robotics. In brief, synthesis user-defined artificial nano-objects based on employing molecules with custom lengths and sequences as building materials that predictably assemble together by obeying Watson–Crick base pairing rules. The general workflow creating nanoshapes getting more straightforward, some objects can be designed automatically from top down. versatile serve tools interface example, therapeutics diagnostics dynamic logic-gated nanopills, light-, pH-, thermally driven devices. Such diverse apparatuses also optical polarizers, sensors capsules, autonomous cargo-sorting robots, rotary machines, precision measurement tools, well electric magnetic-field directed robotic arms. this review, we summarize recent progress nanostructures, mechanics, their various implementations.

Abstract Detecting small sequences of RNA in biological samples such as microRNA or viral demands highly sensitive and specific methods. Here, a reconfigurable DNA origami template has been used where chiral arrangement gold nanorods on the structure can lead to generation strong circular dichroism (CD). Switching cross‐like is achieved by addition nucleic acid sequences, which arrests one possible states molecular recognition. A sequence thus be detected through resulting changes plasmonic CD spectrum. We show selective detection target from hepatitis C virus genome. The binds complementary that part lock mechanism, leads formation defined state system with distinct optical response. With this approach, we were able detect at concentrations low 100 p m .

Abstract Biological structures are inherently complex in nature. Structural hierarchy, chemical anisotropy, and compositional heterogeneity ubiquitous biological systems play a key role the functionality of living systems. For decades, methods such as soft lithography have enabled recreation arrangements through precise spatial control molecular patterns 2D. With technological advances increasing understanding structural biology, there has been an interest recreating organizations 3D. In this review, comprehensive summary latest technologies being used to create 3D functional molecules within hydrogels for tissue engineering applications is presented. The review divided into five groups defined according main driving force fabricate including light, design, microfluidics, printing, non‐contact forces (i.e. electric, magnetic, or acoustic fields self‐assembly).

DNA nanostructures with programmable nanoscale patterns has been achieved in the past decades, and molecular information coding (MIC) on those designed gained increasing attention for security. However, achieving steganography cryptography synchronously remains a challenge. Herein, we demonstrated MIC reconfigurable origami domino array (DODA), which can reconfigure intrinsic but keep DODA outline same steganography. When set of keys (DNA strands) are added, cryptographic data be translated into visible within DODA. More complex ASCII code 6×6 lattice is to demosntrate versatility Furthermore, an anti-counterfeiting approach based conformational transformation-mediated toehold strand displacement reaction protect from decoding falsification.
