Masanori Hara Group
The Laboratory for Biomembranes and Drug Delivery Systems
Our goal is to understand the intermolecular and interfacial interactions of materials, and particularly of self-assembling materials, with the biological milieu, and to combine this knowledge with engineering principles to design successful devices to promote human health. Translational research on testing and optimization of these devices as diagnostics and therapeutics for medical applications is of special significance to our work.
Our research is focused on investigating heterogeneous lipid bilayers with a threefold goal: (I) to contribute to the fundamental understanding of the molecular and supramolecular interactions in heterogeneous lipid membranes, of how these interactions affect collective properties of heterogeneous bilayers, and of how these interactions result in assembling materials with interesting properties, (II) to engineer devices/strategies based on these materials that can be tuned to perform specific tasks, and (III) to translate and optimizethese devices in the form of lipid-based nanoparticles as carriers of diagnostics and therapeutics for medical applications with special focus on cancer.
We have static and dynamic light scattering instruments. Both the size/shape and the motion of particles (for example, polymers and nanoparticles) can be determined with those instruments.
Celik Catalysis Group
Experimental Resources: The catalysis and reaction engineering laboratories include a gas-phase kinetic reactors for evaluation of solid catalysts at ambient and moderate pressures using gas chromatography (Agilent 7890B GC with FID and TCD detectors) and mass spectrometry (Agilent 5977A GCMS) for steady-state and temporal reaction product analysis and product identification. In situ spectroscopy allows for study of solid samples under reaction conditions and reactant gas flows, including transmission and diffuse-reflectance infrared spectroscopy (Thermo Nicolet iS50 FTIR) and diffuse reflectance UV-visible spectroscopy (Thermo Evolution 300).
Additional resources in related labs include high-pressure liquid chromatography, gas adsorption, scanning and tunneling electron microscopies, energy dispersive x-ray spectroscopy, solid-state magic angle spinning nuclear magnetic resonance spectroscopy, x-ray diffraction, and x-ray photoelectron spectroscopy.
Computational Resources: We have constructed an 18 node Beowulf-class computing cluster with dual core processors, 4 TB of storage space, and a 1 Gbps network. Additionally, we have access to several computing clusters on campus, including the Rutgers Engineering Computational Cluster (30 dual core nodes), the School of Engineering computing cluster (48 16-core nodes, InfiniBand network), and the CBE computing cluster (8 16-core nodes, InfiniBand network). All clusters are equipped with MPI for parallel computing.
Asefa laboratory has synthetic equipment to prepare nanomaterials, including vacuum lines, centrifuges, ultrasonicators, rotavaps, and Millipore water purification system, ovens and several eight-step temperature programmable tube furnaces (various models).
The laboratory additionally has a thermogravimetric analyzer (TGA) (Q500, TA Instruments) to study the composition of the materials; gas-chromatograph – mass spectrometer (GC-MS, HP 5972); a gas chromatograph (GC, Agilent) equipped with different types of columns to allow detection of various samples; a potentiostat (PAR 273A, Princeton Applied Research) equipped with a Faraday cage, and all the necessary software to do impedance spectroscopy, cyclic voltammetry, photoelectrochemistry, etc., a UV-Vis-NIR spectrometer (Lambda 950, PerkinElmer) for optical absorption measurements of samples in solution, in solid-state or and in thin film form with wavelength up to the near infrared region (200-3000 nm wavelength); and a gas adsorption instrument (Micromeritics Tristar 3000) for measurement of low relative pressure and high resolution surface area, for determination of pore diameter and pore size distribution of nanoporous materials.
The Glycans, Glycoconjugates, & Glycan Active Enzymes Engineering Laboratory led by Dr. Chundawat at Rutgers is focused on glycans (or carbohydrates), carbohydrate-active enzymes and their application to bioenergy, biomedical, and biomaterials relevant problems.
