Multicopper Laccase Mimicking Nanozymes with Nucleotides as Ligands
Liang, Hao; Lin, Feifei; Zhang, Zijie; Liu, Biwu; Jiang, Shuhui; Yuan, Qipeng; Liu, Juewen (American Chemical Society, 2017-01-18)Using nanomaterials to achieve functional enzyme mimics (nanozymes) is attractive for both applied and fundamental research. Laccases are multicopper oxidases highly important for biotechnology and environmental remediation. ... -
Orthogonal Adsorption Onto Nano-Graphene Oxide Using Different Intermolecular Forces for Multiplexed Delivery
Wang, Feng; Liu, Biwu; Ip, Alexander C-F.; Liu, Juewen (Wiley, 2013-05-31)Nano-graphene oxide can adsorb both doxorubicin and zwitterionic dioleoyl-sn-glycero-3-phosphocholine (DOPC) liposomes in an orthogonal and non-competing manner with high capacities based on different surface and intermolecular ... -
Oxidation Level-Dependent Zwitterionic Liposome Adsorption and Rupture by Graphene-based Materials and Light-Induced Content Release
Ip, Alexander C-F.; Liu, Biwu; Huang, Po-Jung Jimmy; Liu, Juewen (Wiley, 2013-04-08)Liposomes may be stably adsorbed or ruptured on graphene-based materials, depending on the oxidation state of graphene. IR-induced liposome leakage is achieved, since graphene oxide does not induce liposome leakage spontaneously. -
Parallel Polyadenine Duplex Formation at Low pH Facilitates DNA Conjugation onto Gold Nanoparticles
Huang, Zhicheng; Liu, Biwu; Liu, Juewen (American Chemical Society, 2016-11-15)DNA-functionalized gold nanoparticles (AuNPs) have been extensively used in sensing, drug delivery, and materials science. A key step is to attach DNA to AuNPs, forming a stable and functional conjugate. Although the ... -
Parts-per-Million of Polyethylene Glycol as a Non-Interfering Blocking Agent for Homogeneous Biosensor Development
Liu, Biwu; Huang, Po-Jung Jimmy; Zhang, Xu; Wang, Feng; Pautler, Rachel; Ip, Alexander C-F.; Liu, Juewen (American Chemical Society, 2013-11-05)Many homogeneous assays are complicated by the adsorption of probe molecules by the surface of reaction vessels, which are often made of polypropylene or polystyrene-based plastics. To solve this problem, many protein and ... -
Polarity Control for Nonthiolated DNA Adsorption onto Gold Nanoparticles
Zhang, Xu; Liu, Biwu; Servos, Mark R.; Liu, Juewen (American Chemical Society, 2013-05-21)Gold nanoparticles (AuNPs) functionalized with thiolated DNA have enabled many studies in nanoscience. The strong thiol/gold affinity and the nanoscale curvature of AuNPs allow the attached DNA to adapt an upright conformation ... -
Profiling Metal Oxides with Lipids: Magnetic Liposomal Nanoparticles Displaying DNA and Proteins
Wang, Feng; Zhang, Xiaohan; Liu, Yibo; Lin, Zhi Yuan (William); Liu, Biwu; Liu, Juewen (Wiley, 2016-09-19)Metal oxides include many important materials with various surface properties. For biomedical and analytical applications, it is desirable to engineer their biocompatible interfaces. Herein, a phosphocholine liposome (DOPC) ... -
Rationally Designed Nucleobase and Nucleotide Coordinated Nanoparticles for Selective DNA Adsorption and Detection
Wang, Feng; Liu, Biwu; Huang, Po-Jung Jimmy; Liu, Juewen (American Chemical Society, 2013-12-17)Nanomaterials for DNA adsorption are useful for sequence-specific DNA detection. Current materials for DNA adsorption employ electrostatic attraction, hydrophobic interaction, or π–π stacking, none of which can achieve ... -
Reversible gating of ion transport through DNA-functionalized carbon nanotube membranes
Shadmehr, Samaneh; Coleman, Michael; Liu, Biwu; Liu, Juewen; Tang, Xiaowu (Shirley) (Royal Society of Chemistry, 2017-01-03)Carbon nanotubes (CNTs) can be used to create unique fluidic systems for studying ion transport in nanochannels due to their well-defined geometry, atomically smooth and chemically inert surface, and similarity to transmembrane ...
