Computational Design and Optimization of Bone Tissue Engineering Scaffold Topology

N. P. Uth [1], J. Mueller [2], B. Smucker [3], A. Yousefi [1],
[1] Department of Chemical, Paper, and Biomedical Engineering, Miami University, Oxford, OH, USA
[2] Research Computing Support, Miami University, Oxford, OH, USA
[3] Department of Statistics, Miami University, Oxford, OH, USA

Introduction: Bone tissue has a limited ability for regeneration; critically sized defects cannot self-heal and require medical intervention. Bone tissue engineering (TE) circumvents this issue by growing replacement bone tissue from the patient’s own cells inside scaffolds. TE scaffolds ... En savoir plus

PDT Study Using a Model Incorporating Initial Oxygen Concentration and Blood Flow Increase

R. Penjweini[1], T. C. Zhu[1],
[1] Department of Radiation Oncology, University of Pennsylvania, Philadelphia, PA, USA

Introduction: Type II photodynamic therapy (PDT) is an experimental modality for cancer treatment based on the combined action of a photosensitizing drug (photosensitizer), a special wavelength of light and singlet oxygen (1O2) generation; the cell killing is caused by the reaction of ...

Transport Phenomena in the Conversion of an Anaerobic Landfill into an Aerobic Landfill

H. Omar [1], S. Rohani [1],
[1] University of Western Ontario, London, ON, Canada

The world’s landfills are beginning to fill up due to the growing human population. Landfills require land and there will come a time when there will be no land to be used for landfills. A solution that is gaining attraction is the conversion of traditional “dry-tomb” landfills (used for ... En savoir plus

Magnetic Heating of Iron Oxide Nanoparticles with Alternating Magnetic Field for Hyperthermia Applications

N. M. Sundaram[1], M. Sneha[1], R. S. Vishnu[1], M. Alagappan[1]
[1]PSG College of Technology Coimbatore, Tamil Nadu, India

The current therapies available to treat cancer patients are surgical operation and chemo therapy. The drawbacks are the side effects caused by these therapies. Hyperthermia is a treatment technique based on deactivation of cancer cells by raising the temperature in the range of 43 ºC ... En savoir plus

Design and Strain Analysis of Artificial Femoral Head and Stem

N. M. Sundaram[1], M. Sneha[1], A. Kandaswamy[1], R. Nithya[2]
[1]PSG College of Technology, Coimbatore, Tamil Nadu, India
[2]Dr. N.G.P. Institute of Technology, Coimbatore, Tamil Nadu, India

The majority of elderly patients are subjected to hip bone replacement due to dislocation of bone, mechanical failure and infection. The life time of the implant varies from patient to patient depending on their daily physical activity. Once the implant fails, re-operation of hip bone ... En savoir plus

Design and Optimization of Cholesterol Biosensor

N. M. Sundaram[1], M. Alagappan[1]
[1]PSG College of Technology Coimbatore, Tamil Nadu, India

Cholesterol is an essential lipid for human body. The desired total plasma cholesterol for an individual is less than 5.2 mM (200 mg/dL) and it poses a potential health threat when the level is greater than 6.2 mM (240 mg/dL) [1]. Excessive plasma cholesterol causes poor cardiovascular ... En savoir plus

Some Commonly Neglected Issues Which Affect DEP Applications

G. Zhang[1], V. Pandian[1], J. Brcka[2], J. Faguet[2], E. Lee[2]
[1]Clemson University, Clemson, SC, USA
[2]TEL U.S. Holdings, Inc., U.S. Technology Development Center, Austin, TX, USA

Dielectrophoresis (or DEP) has been exploited for various micro and nano fluidics applications like patterning, sorting and separation. However, there are several commonly neglected issues in quantifying DEP forces. Such negligence could potentially lead to wrong DEP force predictions ... En savoir plus

Actively Controlled Ionic Current Gating In Nanopores

G. Zhang[1], S. Bearden[1]
[1]Clemson University, Clemson, SC, USA

It is necessary to understand and control nanopore behavior in order to develop biosensors for a variety of applications including DNA sequencing. The fluidics of nanopore devices we fabricated exhibits a range of interesting phenomena, such as enhanced conductance and current ... En savoir plus

Elucidating the Mechanism Governing the Cell Rotation Behavior Under DEP

G. Zhang[1], Y. Zhao[1], J. Brcka[2], J. Faguet[2], E. Lee[2]
[1]Clemson University, Clemson, SC, USA
[2]TEL U.S. Holdings, Inc., U.S. Technology Development Center, Austin, TX, USA

In our experiments with manipulating cells with DEP, we noted that some cells are constantly spining. By hypothesing that the cell spining is caused by the non-circular shape of the cell body and the off-centered location of its nucleus and that the rotation direction depends on the ...

Improving Detection Sensitivity for Nanoscale Targets Through Combined Photonic and Plasmonic Techniques

G. Zhang[1], Y. Zhao[1]
[1]Clemson University, Clemson, SC, USA

Photonic technique such as the whispering gallery mode (WGM) is often used for detection of small particles like bacteria and viruses. It offers good detection sensitivity and is advantageous over other detection techniques because the detection can be label free. However, the detection ... En savoir plus
