The purpose of this work is to synthesize Mn-Fe heterodoped ZnSe tetrapod nanocrystals (NCs) as dual-mode MRI contrast agent to offer synergetic beneficial over the single contrast tracer. Also, in vivo feasibility of the Mn-Fe heterodoped ZnSe tetrapod NCs as a dual-mode contrast agent has been studied.

Free standing layer-by-layer films of polyethyleneimine and poly(l-lysine) for potential use in corneal stroma engineering Altay, Gizem; Hasırcı, Vasıf Nejat; Khademhosseini, Ali; Department of Biomedical Engineering (2011) In this study we fabricated free standing multilayer films of polyelectrolyte complexes for potential use in tissue engineering of corneal stroma by using the layer-by-layer (LbL) approach. In the formation of these LbL films negatively charged, photocrosslinkable (methacrylated) hyaluronic acid (MA-HA) was used along with polycations polyethyleneimine (PEI) and poly(L-lysine) (PLL). Type I collagen (Col) was blended in with PLL for improving the water absorption and cell attachment properties of the films....
Polyelectrolyte multilayer films as substrates for photoreceptor cells Tezcaner, Ayşen; Boulmedais, F; SAHEL, JOSE; SCHAAF, PIERRE; VOEGEL, JEAN CLAUDE; LAVALLE, PHILIPPE (2006-01-01) Reconstruction of extracellular matrix substrates for delivery of functional photoreceptors is crucial in pathologies such as retinal degeneration and age-related macular degeneration. In this study, we assembled polyelectrolyte films using the layer-by-layer deposition method. The buildup of three different films composed of poly(L-lysine)/ chondroitin sulfate (PLL/CSA), poly(L-lysine)/poly(styrenesulfonate) (PLL/PSS), or poly(L-lysine)/hyaluronic acid (PLL/HA) was followed by means of quartz crystal micro...
Contrast Enhancement of Microscopy Images Using Image Phase Information Çakır, Serhat; Atalay, Rengül; ÇETİN, AHMET ENİS (2018-01-01) Contrast enhancement is an important preprocessing step for the analysis of microscopy images. The main aim of contrast enhancement techniques is to increase the visibility of the cell structures and organelles by modifying the spatial characteristics of the image. In this paper, phase information-based contrast enhancement framework is proposed to overcome the limitations of existing image enhancement techniques. Inspired by the groundbreaking design of the phase contrast microscopy (PCM), the proposed ima...
Magnetohydrodynamic flow imaging of ionic solutions using electrical current injection and MR phase measurements Eroglu, Hasan H.; Sadighi, Mehdi; Eyüboğlu, Behçet Murat (Elsevier BV, 2019-06-01) In this study, a method is proposed to image magnetohydrodynamic (MHD) flow of ionic solutions, which is caused by externally injected electrical current to an imaging media, during MRI scans. A multi-physics (MP) model is created by using the electrical current, laminar flow, and MR equations. The conventional spoiled gradient echo MRI pulse sequence with bipolar flow encoding gradients is utilized to encode the MHD flow. Using the MP model and the MRI pulse sequence, relationship between the MHD flow rela...
Application of sar techniques in an ultrasound testbed Solak, Güven; Tuncer, Temel Engin; Department of Electrical and Electronics Engineering (2008) In this thesis, an ultrasound testbed is designed in order to practice the Synthetic Aperture Radar (SAR) techniques. The thesis work is built on the fundamentals of SAR theory. In this respect, four different methods for the reconstruction of SAR image are considered. The ultrasonic testbed is composed of a mobile vehicle where the ultrasound transmitter and receiver are mounted. An analog circuit is designed in order to condition the transmitted and received signals. The receiving signal is processed in a...
