Crossing the blood–brain barrier with carbon dots: uptake mechanism andin vivocargo delivery

“…[12][13][14] In addition, CDs display high water dispersibility, good biocompatibility, and nontoxicity. 15 Moreover, CDs' surfaces can also easily be decorated with molecules such as uorophores and drugs. 16 Considering these merits, CDs are very promising drug nanocarriers for future drug delivery.…”

Assemblies of Polyacrylonitrile-Derived Photoactive Polymers as Blue and Green Light Photo-Cocatalysts for Cu-Catalyzed ATRP in Water and Organic Solvents

“…As alternatives to traditionally used transition metal complexes, organic photocatalysts (OPC) have received great attention, due to their low cost, highly tunable structures and photophysical properties ( Romero and Nicewicz, 2016 ). More recently, organic photoactive nanostructured objects (OPNO) have emerged as promising materials owing to the growing interest in combining organic chemistry and nanotechnology ( Han et al, 2018 ; Zhang et al, 2020 ). OPNO can span the range from covalently bonded “carbon dots” ( Sun et al, 2006 ) to “polymer dots” ( Zhu et al, 2015a ; Zhu et al, 2015b ; Tao et al, 2019 ; Xia et al, 2019 ) held together via non-covalent interactions.…”

“…Second, reactions using long-wavelength irradiations (other than blue or UV light) were underexplored, despite the advantages of long-wavelength irradiations, such as better penetration depths ( Romero and Nicewicz, 2016 ; Han et al, 2018 ). Overcoming these limitations is necessary for expanding the applications of OPNO-based OPCs, obtaining deeper understandings of the photocatalytic mechanism, and economizing the photocatalytic processes ( Zhang et al, 2020 ).…”

N-Doped Carbon Dots Derived from Melamine and Triethanolamine for Selective Sensing of Fe3+ Ions

“…But all the techniques mentioned above have drawbacks such as severe synthetic conditions, high cost, complex, and time-consuming processes [21][22][23]. Even though many other methods are available to synthesize nitrogen-doped carbon dots (NCDs) [24][25][26], for example, using biomass via green synthesis methods, -broad PL emission profiles and high quantum yields remained as challenges in the production of CDs. So, the development of inexpensive and scalable synthesis for the production of NCDs remains a requirement.…”
