Preparation of boronic acid–modified polymer dots under mild conditions and their applications in pH and glucose detection

One‐Step Hydrothermal Synthesis of Boric Acid‐Functionalized Carbon Dots and their Applications in Glucose Sensing

“…[24,25] In our previous studies, boronic acid-modified polymer dots (B-PDs) were fabricated by a "synthesis-modification integration" route utilizing polyethylenimine (PEI) and phenylboronic acid as precursors for the first time. [26] The applications in actual human blood and glucose injection samples confirmed satisfactory results. However, the quantum yield is only 8.69 % and the response time is up to 40 min.…”

“…It is well known that boronic acid is one of the generically used identification sites for monosaccharide molecules [24,25] . In our previous studies, boronic acid‐modified polymer dots (B‐PDs) were fabricated by a “synthesis‐modification integration” route utilizing polyethylenimine (PEI) and phenylboronic acid as precursors for the first time [26] . The applications in actual human blood and glucose injection samples confirmed satisfactory results.…”

A latent reversible ratiometric optical pH sensing probe based on phenylboronic acid for alkaline pH detection and applications in test paper and alkalotic HK-2 cells

“…Boric acid is a promising candidate as a pH-sensitive agent. [18][19][20] To date, a lot of boronic acid-based hydrogels have been designed and applied in the biological field for pH-regulated healing. [21][22][23][24] Additionally, the pH-controlled interaction between boronic acid and diol moieties is of great convenience for saccharide and nucleic acid sensing.…”

Fluorescein-Functionalized Conjugated Polydiacetylenes with Excellent Reversible Thermochromic Properties under Thermal and 980 nm Near-Infrared Light Stimuli

“…In nature, chromism is a significant phenomenon found in many biological systems, such as chameleons, Kallima inachus, Pacific tree frogs, and octopuses, which can adjust the colors of the skin in response to external stimuli. , Therefore, scientists have been inspired by enormous interest in the development of stimulus-responsive colorimetric materials. Among these materials, conjugated polymers have been widely investigated owing to their extensively delocalized π-electron networks as well as unique optical and electric properties. − The special structures endow the conjugated material with excellent sensitive properties to environmental stimuli, which make them ideal candidates in the design of chemical and biological sensors. − …”
