Dear Customer:

The current international situation is complex and volatile, and uncertain tariff policies may potentially impact our product prices. Given these uncertainties, we value your understanding regarding order-related matters.

If you decide to place an order during this period, we reserve the right to adjust the price based on the evolving situation. We understand that market changes may cause inconvenience. We will negotiate with you if there’s a significant price fluctuation due to tariff policy changes before the order’s actual delivery, and in such cases we may adjust or cancel the order as necessary.

一般描述

羧酸官能化的GNPs由于蛋白质的带负电荷的羧酸酯基团和带正电荷的氨基之间的静电吸引而与各种蛋白质分子形成结合物。[1]

应用

功能化颗粒已被广泛用于研究纳米颗粒[2]的细胞摄取和靶向药物递送[3]
羧酸基团与各种蛋白质结合,用于靶向药物递送和基因治疗。[4]
金纳米颗粒直径30 nm,羧酸功能化,PEG 3000包被,OD 50,分散在H2O中,可潜在用于生物传感器的开发、癌细胞成像、药物递送和光热疗法。[5]
AuNPs也可用于抗体的固定化,以提高光纤传感器对COVID-19筛查的敏感性。[6]它还可以在钛电极上沉积,形成用于DNA杂交电化学检测的小型化设备。[6]

特点和优势

降低细胞毒性并提高GNP在靶向药物递送中的效率。PEG增加了纳米颗粒的稳定性并防止了团聚。[4]
