Abstract
Infectious outbreaks are the foremost global public health concern, challenging the current healthcare system, which claims millions of lives annually. The most crucial way to control an infectious outbreak is by early detection through point-of-care (POC) diagnostics. POC diagnostics are highly advantageous owing to the prompt diagnosis, which is economical, simple and highly efficient with remote access capabilities. In particular, utilization of nanomaterials to architect POC devices has enabled highly integrated and portable (compact) devices with enhanced efficiency. As such, this review will detail the factors influencing the emergence of infectious diseases and methods for fast and accurate detection, thus elucidating the underlying factors of these infections. Furthermore, it comprehensively highlights the importance of different nanomaterials in POCs to detect nucleic acid, whole pathogens, proteins and antibody detection systems. Finally, we summarize findings reported on nanomaterials based on advanced POCs such as lab-on-chip, lab-on-disc-devices, point-of-action and hospital-on-chip. To this end, we discuss the challenges, potential solutions, prospects of integrating internet-of-things, artificial intelligence, 5G communications and data clouding to achieve intelligent POCs.

Abstract
A combination of X-ray photoelectron spectroscopy (XPS), high-resolution XPS, near-edge X-ray absorption fine structure (NEXAFS) spectroscopy, and sum-frequency-generation (SFG) spectroscopy was used to monitor two types of ssDNA films on Au(111) before and after hybridization. As probe systems, films of thiolated and block-oligonucleotides were used, taking thiolated thymine d(T) homo-oligonucleotides and thymine-adenine d(A-T) diblock-oligonucleotides as representative examples. In accordance with previous work, hybridization of the shorter and more densely packed thiolated ssDNA films produced fewer (if any) hybrids, whereas the longer and less densely packed layers exhibited a larger hybridization yield. The above effects were less pronounced in the case of the d(A-T) films where the hybridization yield of the less densely packed monolayers was significantly lower. This was presumably due to the formation of internal dimeric hybrids in the immobilization step of the probe molecules, resulting in the generation of fewer probe-target hybrids upon exposure to the target molecules. In all ssDNA films displaying a reasonable number of hybrids present, significant orientational changes were observed and could be monitored in detail. These results suggest that the given combination of spectroscopic techniques can be a valuable tool to gain molecular-level information about hybrids at interfaces.

Abstract
Peptide nucleic acid (PNA) is the modified DNA or DNA analogue with a neutral peptide backbone instead of a negatively charged sugar phosphate. PNA exhibits chemical stability, resistant to enzymatic degradation inside living cell, recognizing specific sequences of nucleic acid, formation of stable hybrid complexes like PNA/DNA/PNA triplex, strand invasion, extraordinary thermal stability and ionic strength, and unique hybridization relative to nucleic acids. These unique physicobiochemical properties of PNA enable a new mode of detection, which is a faster and more reliable analytical process and finds applications in the molecular diagnostics and pharmaceutical fields. Besides, a variety of unique characteristic features, PNAs replace DNA as a probe for biomolecular tool in the molecular genetic diagnostics, cytogenetics, and various pharmaceutical potentials as well as for the development of sensors/arrays/chips and many more investigation purposes. This review paper discusses the various current aspects related with PNAs, making a new hot device in the commercial applications like nanobiosensor arrays.

Abstract
Many polypeptides and small proteins can be readily engineered such that they only fold upon binding a specific target ligand. This approach couples target recognition with a considerable change in polymer structure and dynamics. Recent years have seen the development of a number of biosensors that couple these large changes to readily measurable optical (fluorescent) outputs. These sensors afford the detection of a wide variety of macromolecular targets including proteins, polypeptides, and nucleic acids. Here we describe the design of such biosensors, from the first iterations as protein engineering experiments, to the development of biosensors targeting a range of protein and nucleic acid targets.

Abstract
DNA microarrays are an important tool with a variety of applications in gene expression studies, genotyping, pharmacogenomics, pathogen classification, drug discovery, sequencing and molecular diagnostics. They are having a strong impact in medical diagnostics for cancer, toxicology and infectious disease applications. A series of papers have been published describing DNA biochips as alternative to conventional microarray platforms to facilitate and ameliorate the signal readout. In this review, we will consider the different methods proposed for biochip construction, focusing on electrochemical detection of DNA. We also introduce a novel single-stranded DNA platform performing high-throughput SNP detection and gene expression profiling.

Abstract
The surface structure and DNA hybridization performance of thiolated single-strand DNA (HS-ssDNA) covalently attached to a maleimide-ethylene glycol disulfide (MEG) monolayer on gold have been investigated. Monolayer immobilization chemistry and surface coverage of reactive ssDNA probes were studied by X-ray photoelectron spectroscopy and time-of-flight secondary ion mass spectrometry. Orientation of the ssDNA probes was determined by near-edge X-ray absorption fine structure (NEXAFS). Target DNA hybridization on the DNA-MEG probe surfaces was measured by surface plasmon resonance (SPR) to demonstrate the utility of these probe surfaces for detection of DNA targets from both purified target DNA samples and complex biological mixtures such as blood serum. Data from complementary techniques showed that immobilized ssDNA density is strongly dependent on the spotted bulk DNA concentration and buffer ionic strength. Variation of the immobilized ssDNA density had a profound influence on the DNA probe orientation at the surface and subsequent target hybridization efficiency. With increasing surface probe density, NEXAFS polarization dependence results (followed by monitoring the N 1s --> pi* transition) indicate that the immobilized ssDNA molecules reorient toward a more upright position on the MEG monolayer. SPR assays of DNA targets from buffer and serum showed that DNA hybridization efficiency increased with decreasing surface probe density. However, target detection in serum was better on the "high-density" probe surface than on the "high-efficiency" probe surface. The amounts of target detected for both ssDNA surfaces were several orders of magnitude poorer in serum than in purified DNA samples due to nonspecific serum protein adsorption onto the sensing surface.

Genital HPV types have been subdivided into medium-low risk, and high-risk (HPV 16 and 18), frequently associated with cervical cancer. Three DNA-based piezoelectric biosensors were here developed for a quick detection and genotyping of HPV. METHODS We developed a method for the detection and genotyping of HPV in human cervical scraping samples based on coupling DNA piezoelectric sensors with Polymerase Chain Reaction (PCR). The novelty of this work was the design and immobilisation of a degenerate probe (chosen in a conserved region of the viral genome) for the simultaneous detection of 16 virus strains and of two specific probes (chosen in a less-conserved region of the viral genome) for genotyping. RESULTS The three biosensors were optimised with synthetic oligonucleotides with good reproducibility (HPVdeg CV% (av) 9%, HPV16 CV%(av) 9%; HPV18 CV%(av) 11%) with a detection limit of 50 nM. Cervical scraping samples after PCR amplification (in 40-200 nM range), were tested without the need of label with high selectivity and reproducibility. The results were in agreement with a reference method used in routinary analysis. CONCLUSION Piezoelectric biosensors have proven to be suitable for detection and genotyping of HPV.

Abstract
The interaction of drugs with DNA is an important aspect in pharmacology. In recent years, many important technological advances have been made to develop new techniques to monitor biorecognition and biointeraction on solid devices. The interaction between DNA and drugs can cause chemical and conformational modifications and, thus, variation of the electrochemical properties of nucleobases. The propensity of a given compound to interact with DNA is measured as a function of the decrease of guanine oxidation signal on a DNA electrochemical biosensor. Covalent binding at N7 of guanine, electrostatic interactions, and intercalation are the events that this kind of biosensor can detect. In this context, the interaction between a panel of antitumoral Pt-, Ru-, and Ti-based metallodrugs with DNA immobilized on screen-printed electrodes has been studied. The DNA biosensors are used for semiquantitative evaluation of the analogous interaction occurring in the biological environment.

Abstract
Nucleic acids include substantial information in their base sequence and their hybridization-complexation motifs. Recent research efforts attempt to utilize this biomolecular information to develop DNA nanostructures exhibiting machine-like functions. DNA nano-assemblies revealing tweezers, motor, and walker activities exemplify a few such machines. The DNA-based machines provide new components that act as sensitive sensors, transporters, or drug delivery systems.
