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.

应用

功能化颗粒已广泛用于研究纳米颗粒的细胞摄取和靶向药物递送。
Amine functionalized, PEG 3000 coated, OD 50, and H2O dispersed gold nanoparticles (5 nm) can be used in the activation of silica nanosphere for the decomposition of formic acid.[1] They may be used in the radiosensitization and imaging of cancer cells.[2]
AuNPs can be potentially immobilized on antibodies to improve the sensitivity of optical fiber sensors for the screening of COVID-19.[3] They can also be deposited on the titanium electrode for the formation of a miniaturized device for the electrochemical detection of DNA hybridization, which can be used in the diagnosis of COVID-19.[3]

特点和优势

  • Negatively charged siRNA-PEG complex which is attached to positively charged GNPs is easily cleavable in reductive cytosolic environment thus enabling the release of siRNA into cytosol.
  • Decreases the cytotoxicity and increases efficiency of GNPs. PEG increases the stability of the nanoparticles and prevents agglomeration.[4]
