Abstract
Fast, cheap and easy to use nucleic acids detection methods are crucial to mitigate adverse impacts caused by various pathogens, and are essential in forensic investigations, food safety monitoring or evolution of infectious diseases. We report here a method based on the α-hemolysin (α-HL) nanopore, working in conjunction to unmodified citrate anion-coated gold nanoparticles (AuNPs), to detect nanomolar concentrations of short single-stranded DNA sequences (ssDNA). The core idea was to use charge neutral peptide nucleic acids (PNA) as hybridization probe for complementary target ssDNAs, and monitor at the single-particle level the PNA-induced aggregation propensity AuNPs during PNA–DNA duplexes formation, by recording ionic current blockades signature of AuNP–α-HL interactions. This approach offers advantages including: (1) a simple to operate platform, producing clear-cut readout signals based on distinct size differences of PNA-induced AuNPs aggregates, in relation to the presence in solution of complementary ssDNAs to the PNA fragments (2) sensitive and selective detection of target ssDNAs (3) specific ssDNA detection in the presence of interference DNA, without sample labeling or signal amplification. The powerful synergy of protein nanopore-based nanoparticle detection and specific PNA–DNA hybridization introduces a new strategy for nucleic acids biosensing with short detection time and label-free operation.

Abstract
Nanopore technology has been employed as a powerful tool for DNA sequencing and analysis. To extend this method to peptide sequencing, a necessary step is to profile individual amino acids (AAs) through their nanopore stochastic signals, which remains a great challenge because of the low signal-to-noise ratio and unpredictable conformational changes of AAs during their translocation through nanopores. We showed that the combination of an N-terminal derivatization strategy of AAs with nanopore technology could lead to effective in situ differentiation of AAs. Four different derivatization reactions have been tested with five selected AAs: Ala, Phe, Tyr, His, and Asp. Using an α-hemolysin nanopore, we demonstrated the feasibility of derivatization-assisted identification of AAs regardless of their charge composition and polarity. The method was further applied to discriminate each individual AA in testing data sets using their established nanopore profiles from training data sets. We envision that this proof-of-concept study will not only pave a way for identification of individual AAs but also lead to future applications in protein/peptide sequencing using the nanopore technology.

Abstract
Both vascular endothelial growth factor (VEGF) and matrix metallopeptidase-9 (MMP-9) are key biomarkers in tumor angiogenesis. Determination of the overexpression of the two biomarkers would provide valuable information on the progression of tumor growth and metastasis, but their simultaneous quantification by a single probe is unprecedented. Here, we develop a triplex DNA-based nanoprobe for simultaneously quantifying VEGF and MMP-9 using an α-hemolysin nanopore. A DNA aptamer is used as the triplex molecular beacon (tMB) loop to bind VEGF, and a stem-forming oligonucleotide modified with a short peptide is used to recognize MMP-9. The sequential presence of VEGF and MMP-9 could also be identified by different patterns of current events. Besides, the characteristic current events generated by the DNA probe possess pH-dependent patterns that can be used to reflect the environmental pH. Success in the construction of such DNA nanoprobes will greatly facilitate the investigation of the mechanisms of different tumor angiogenesis processes and provide a useful approach for cancer diagnosis.

Abstract
The shape and structure analyses capability of nanopore is powerful and complementary to mass spectrometry analysis. It is extremely attractive but challenging to integrate these two techniques. The feasibility of combining nanopore electrospray with mass spectrometry was explored in this study. A nanopore effect was observed during the nano-electrospray of single bacterium, through which the shape and dimension of a single bacterium could be obtained. Molecular information on these bacteria was then acquired by analyzing these bacteria deposited on the counter electrode through laser spray ionization mass spectrometry experiments. Proof-of-concept experiments were carried out for four types of bacteria. Results show that the combination of nanopore results with mass spectrum data could effectively improve the identification accuracy of these bacteria from 72.5% to 100%. Although initial experiments were demonstrated in this work, results showed that it is feasible and promising to integrate nanopore technology with mass spectrometry for large biomolecule studies in the near future.

Abstract
Membrane protein pores have demonstrated applications in nanobiotechnology and single-molecule chemistry for effective detection of biomolecules. Here, we define the molecular basis of carbohydrate polymers translocation through a substrate-specific bacterial nanopore, CymA, which has a 15-residue N terminus segment inside the pore, restricting its diameter. Using single-channel recordings, we determined the kinetics of cationic cyclic oligosaccharide binding and elucidated the translocation mechanism across the pore in real-time. The cationic cyclic hexasaccharide binds to the densely packed negatively charged residues at the extracellular side of the pore with high affinity, facilitating its entry into the pore driven by the applied voltage. Further, the dissociation rate constant increased with increasing voltages, indicating unidirectional translocation toward the pore exit. Specifically, a larger cationic cyclic octasaccharide rapidly blocked the pore more effectively, resulting in the complete closure of the pore with increasing voltage, implying only strong binding. Further, we show that uncharged oligosaccharides exclusively bind to the extracellular side of the pore and the electroosmotic flow most likely drives their translocation. We propose that CymA favors selective translocation of cyclic hexasaccharide and linear maltooligosaccharides due to an asymmetrical charge pattern and the N terminus that regulates the substrate transport. We suggest that this substrate-specific nanopore with sophisticated geometry will be useful for complex biopolymer characterization.

Abstract
DNA lesions such as metholcytosine(mC), 8-OXO-guanine (OG), inosine (I), etc. could cause genetic diseases. Identification of the varieties of lesion bases are usually beyond the capability of conventional DNA sequencing which is mainly designed to discriminate four bases only. Therefore, lesion detection remains a challenge due to massive varieties and less distinguishable readouts for structural variations at the molecular level. Moreover, standard amplification and labeling hardly work in DNA lesion detection. Herein, we designed a single molecule interface from the mutant aerolysin (K238Q), whose sensing region shows high compatibility to capture and then directly convert a minor lesion into distinguishable electrochemical readouts. Compared with previous single molecule sensing interfaces, the temporal resolution of the K238Q aerolysin nanopore is enhanced by two orders, which has the best sensing performance in all reported aerolysin nanopores. In this work, the novel K238Q could discriminate directly at least three types of lesions (mC, OG, I) without labeling and quantify modification sites under the mixed heterocomposition conditions of the oligonucleotide. Such a nanopore electrochemistry approach could be further applied to diagnose genetic diseases at high sensitivity.
