As a positively charged hyperbranched polyamine, PEI not only enhances the stability of the gold nanoclusters but also provides them with strong fluorescence properties across a wide pH range, making them suitable for various biomedical applications.<\/p>\n<p><strong>Features<\/strong><\/p>\n<ul>\n<li><strong>Optical Properties<\/strong>: PEI-Au NCs exhibit fluorescence properties that depend on their size, giving them significant potential for applications in bioimaging and fluorescence probing.<\/li>\n<li><strong>Stability<\/strong>: The encapsulation by PEI gives the gold nanoclusters high stability in physiological environments, reducing aggregation or degradation.<\/li>\n<li><strong>Positive Charge<\/strong>: The positive charge of PEI enables the gold nanoclusters to easily bind with negatively charged materials, increasing their potential for biological applications.<\/li>\n<\/ul>\n<p><strong>Applications<\/strong><\/p>\n<ul>\n<li><strong>Bioimaging<\/strong>: As fluorescent nanomaterials, PEI-Au NCs can be used for cell imaging, tissue imaging, and tumor imaging in biomedical research.<\/li>\n<li><strong>Drug Delivery<\/strong>: PEI-Au NCs can serve as a drug delivery system. Their surface is easy to modify, allowing effective drug loading and targeted delivery.<\/li>\n<li><strong>Chemical Detection<\/strong>: PEI-Au NCs are sensitive to specific chemicals and are widely used in environmental monitoring, food safety, and biomarker detection.<\/li>\n<\/ul>\n<p>&nbsp;<\/p>","protected":false},"excerpt":{"rendered":"[tp_attributes num_attributes=\"5\"]\n<div tabindex=\"0\" role=\"article\" data-tabster=\"{&quot;groupper&quot;:{&quot;tabbability&quot;:2},&quot;focusable&quot;:{}}\" data-content=\"ai-message\" aria-labelledby=\"qCjP5C64NhAdgRPyfetDd-author} qCjP5C64NhAdgRPyfetDd-content-0\">\n<div id=\"qCjP5C64NhAdgRPyfetDd-content-0\">\n<p>PEI-stabilized gold nanoclusters provide optimized fluorescence properties, superior biocompatibility, and enhanced colloidal stability.
