BC@DNA-Mn3(PO4)2 Nanozyme for Real-Time Detection of Superoxide from Living Cells

“…The abundant OH groups of BC help single-chain DNA bind to the surface of BC by hydrogen bonding, allowing the phosphate groups of DNA to effectively anchor onto manganese ions and confine the growth of manganese phosphate. 28,29 As expected, crimped graphene-like BC@DNA-Mn 3 (PO 4 ) 2 microspheres were successfully constructed in our work. For the in situ electrochemical detection of ROS released from living cells, the sensing interface requires high conductivity, excellent electrocatalytic performance, and good biocompatibility and cell adhesion.…”

“…In our featured work, an ultralight bacterial cellulose (abbreviated as BC) aerogel, constructed with nanowires textured with ultrathin layers (Scheme b), was selected as the host material for ultrasmall nanosized manganese phosphate. The abundant OH groups of BC help single-chain DNA bind to the surface of BC by hydrogen bonding, allowing the phosphate groups of DNA to effectively anchor onto manganese ions and confine the growth of manganese phosphate. , As expected, crimped graphene-like BC@DNA-Mn 3 (PO 4 ) 2 microspheres were successfully constructed in our work. For the in situ electrochemical detection of ROS released from living cells, the sensing interface requires high conductivity, excellent electrocatalytic performance, and good biocompatibility and cell adhesion. − To investigate the applicability of our designed BC@DNA-Mn 3 (PO 4 ) 2 microspheres as mimic enzymes, a screen-printed electrode modified with BC@DNA-Mn 3 (PO 4 ) 2 and covered with a microfluidic channel was designed and used to simultaneously culture cells and in situ electrically detect O 2 •– from living cells (Scheme c).…”

“…Because of the abundant OH groups of BC, a single strand of DNA can easily bind to the surface of BC sheets by hydrogen bonding; obvious folds and protuberances can be seen in the SEM image of BC@DNA (Figure 1B). 28 Then, manganese ions were anchored onto the surface of BC@DNA via the phosphate groups of DNA and further rolled into fluffy BC@DNA-Mn 3 (PO 4 ) 2 microspheres (Figure 1C,D). 33,34 The graphenelike thin sheets of BC@DNA-Mn 3 (PO 4 ) 2 were further confirmed by TEM (Figure 1E).…”

Hygroscopic, structural, and thermal properties of essential oil microparticles of sweet orange added with cellulose nanofibrils

“…Properties of cellulose nanofibrils (CNF) depend on the vegetable raw materials and processing methods. Typically, the techniques employ different processes such mechanical disintegration (e.g., grinding, refining, and ultrasonication) (Barbash, Yaschenko, & Shniruk, ; Szymańska‐Chargot et al, ), as well as biological (with specific bacteria and enzymes) and chemical (with acids and alkalis) (Kaya et al, ; Mujtaba, Kaya, et al, ; Mujtaba, Salaberria, et al, ; Mujtaba, Sargin, & Kaya, ), to produce various types of CNF, which differ in morphology, crystallinity, and surface chemistry (Nechyporchuk, Belgacem, & Bras, ; Shak, Pang, & Mah, ; Zhang, Barhoum, Xiaoqing, Li, & Samyn, ).…”

Docetaxel-Loaded Chitosan-Cholesterol Conjugate-Based Self-Assembled Nanoparticles for Overcoming Multidrug Resistance in Cancer Cells

“…In the past few decades, nanoparticles (NPs), based on natural or synthetic polymers, have been widely investigated as drug delivery carriers due to their unique characteristics [ 1 , 2 , 3 , 4 , 5 , 6 , 7 ]. Biocompatible polymers, such as hyaluronic acid, poly(lactic-co-glycolic acid), and cellulose, have been introduced to design NPs for drug delivery.…”
