“…A variation in chirality dependent responses induced by two or more structurally similar molecules will allow for their selective detection by utilizing the responses of several chiralities. Such a strategy may be needed to design SWNT sensors that can effectively discriminate between structurally similar carbohydrate molecules or between various catecholamines and ascorbic acid, both of which remain subjects of ongoing studies [38][39][40][41].…”

a b s t r a c tCorona phase molecular recognition (CoPhMoRe) is a phenomenon whereby a polymer or surfactant corona phase wrapped around a nanoparticle selectively recognizes a particular molecule. The method can potentially generate non-biological, synthetic molecular recognition sites, analogous to antibodies, for a broad range of biomedical applications, including new types of sensors, laboratory and clinical assays, as well as inhibitors and targeted therapeutics. In this work, we utilize near infrared fluorescent single-walled carbon nanotubes (SWNTs) wrapped with specific single stranded DNA sequences to explore the (n,m) chirality dependence of CoPhMoRe. Specific DNA oligonucleotide sequences are known to recognize and interact uniquely with certain (n,m) SWNTs enabling their enrichment in ion exchange chromatography. We explore the CoPhMoRe effect using corona phases constructed from a library of 24 such sequences, screening against a biomolecule panel that includes common neurotransmitters, amino acids, saccharides and riboflavin. Example sequences include (ATT) 4 , (TAT) 4 and (ATTT) 3 which recognize (7,5), (6,5) and (8,4) SWNTs, respectively. We find that these recognition sequences indeed form CoPhMoRe phases that are distinct among SWNT chiralities, and appear to pack more densely as to exclude analyte adsorption on the chirality they recognize. These results have encouraging implications for the controlled design of CoPhMoRe phases for biomedical applications.

“…7,8 Recently, numerous new types of boronic acid sensors have been fabricated to detect blood glucose concentrations, [9][10][11][12][13] ionic compounds, [14][15][16][17] traces of water in solvents, 18,19 hydrogen peroxide (H 2 O 2 ), [20][21][22] catecholamines, 23 as well as using boronic acids as biochemical tools for various applications, including tumor cell imaging, 24,25 enzyme inhibitors 26 and cell delivery systems. 27 Therefore, the boron-based uorescent sensor is still hot in today's research.…”

As Lewis acids, boronic acids can bind with 1,2-or 1,3-diols in aqueous solution reversibly and covalently to form five or six cyclic esters, thus resulting in significant fluorescence changes. Based on this phenomenon, boronic acid compounds have been well developed as sensors to recognize carbohydrates or other substances. Several reviews in this area have been reported before, however, novel boronic acid-based fluorescent sensors have emerged in large numbers in recent years. This paper reviews new boronbased sensors from the last five years that can detect carbohydrates such as glucose, ribose and sialyl Lewis A/X, and other substances including catecholamines, reactive oxygen species, and ionic compounds. And emerging electrochemically related fluorescent sensors and functionalized boronic acid as new materials including nanoparticles, smart polymer gels, and quantum dots were also involved.By summarizing and discussing these newly developed sensors, we expect new inspiration in the design of boronic acid-based fluorescent sensors.

“…5 The majority of boronic acid-based sensing systems developed so far rely on fluorescence spectroscopy for visualizing the binding events. This includes turn-on fluorescence detection, 6 fluorescence quenching, 7 and fluorescence resonance energy transfer (FRET) techniques, 8 which, for instance, have been successfully applied for saccharides, as well as for nucleosides and nucleotides recognition.…”
