Visual sensing of proteins using gold nanoparticles coated with polyphenolic glycoside

Recent progress in 0D optical nanoprobes for applications in the sensing of (bio)analytes with the prospect of global health monitoring and detailed mechanistic insights

“…(Table 5) Seto et al reported the preparation of glucosylrutin-catecholconjugated AuNPs for the selective and specific visual recognition of proteins via an aggregation-induced chromogenic alteration from red to reddish violet. 206 Herein, catechol was beneficial for surface coating, while glycoside helped to bind the targeted biomolecules.…”

“…Recently, AuNPs-based chromo-fluorogenic nanosensors exhibited excellent biological applications towards the target-specific recognition of various bio-analytes, such as protein, DNA, lysozymes, dopamine, biothiols such as cysteine and glutathione, and bio-relevant ions such as Fe 3+ and Fe 2+ etc . 206–232 (Table 5)…”

Bioinspired Polymeric Coating with Self‐Adhesion, Lubrication, and Drug Release for Synergistic Bacteriostatic and Bactericidal Performance

“…Specifically, Δf and Δm/A presented a linear relationship, which could be described within the context of the Sauerbrey theory. [41,42] In this equation, f n was the overtone frequency of the QCM (f n = nf 0 ; n = 3; f 0 = fundamental oscillation frequency), A was the electrode area (0.196 cm 2 ), and ρ c and μ c were the quartz density (2.65 g cm −3 ) and shear modulus (2.947 × 10 11 g (cm s 2 ) −1 , respectively. According to this equation, a frequency change of 1 Hz corresponded to a mass density increase of 0.36 ng cm −2 for the 8.95 MHz QCM used in this study.…”
