In recent studies, in situ reduction of metal nanoparticles (MNPs) has been explored to enhance synthetic efficiency and streamline procedures by employing disaccharides such as lactose [24][25]. However, the potential of monosaccharides

• -aminophenyl boronic acid)/sodium alginate nanogel (Ag@PABA-SA) was synthesized using a green, in situ chemical oxidative polymerization approach for detecting hydrogen peroxide in lake water [115]. When this experiment was carried out without alginate, it showed unsuccessful results. Importantly, with

• alginate present, PABA covalently attached to the hydroxy groups of alginates to form a PABA-SA semi-interpenetrating network on which AgNPs were concurrently deposited (Figure 5). As a result, very stable polymer-based AgNPs were formed. The Ag@PABA-SA nanogel was tested as a colorimetric probe for

Another study employed CD44–hyaluronic acid interaction to endow a diselenide-bridged hyaluronic acid nanogel (SeNG) with the ability to specifically accumulate at CD44-overexpressed inflammatory cells [103]. Both in vitro and in vivo experiments demonstrated that the designed SeNG could not only
