Antibacterial photodynamic therapy with indocyanine green and near-infrared light

Topaloğlu, Nermin. (Thesis (Ph.D.)-Bogazici University. Institute of Biomedical Engineering, 2014., 2014.)

Increase in antibiotic-resistance is a worldwide health problem which may result in septicemia and subsequent death in recent years. Some of these deaths are caused by nosocomial, burn or chronic wound infections. Photodynamic ...
Depth assessment of an absorber in a semi-infinite medium by continuous wave diffuse reflectance

Aksel, Ertuğrul Burteçin. (Thesis (Ph.D.)-Bogazici University. Institute of Biomedical Engineering, 2018., 2018.)

A method to locate an absorber embedded in a semi-in nite turbid medium by spatially-resolved continuous-wave di use re ectance measurements is introduced. The possible of use the method as a priori information in di use ...
Design and development of thulium laser system for medical applications

Bilici, Temel. (Thesis (Ph.D.)-Bogazici University. Institute of Biomedical Engineering, 2012., 2012.)

The Thulium (Tm:YAP) laser is suitable for medical applications due to strong absorption in water. In this thesis, a computer controlled Tm:YAP laser system with a power output up to 1 W and emission wavelength of 1980 nm ...
Design of a dynamic optical property monitoring system: Studying the effect of temperature change

Kara, Ercan. (Thesis (Ph.D.)-Bogazici University. Institute of Biomedical Engineering, 2018., 2018.)

In laser applications, it is necessary to know the tissue optical properties before the treatment and how they change during the treatment. The optical monitoring system with double-integrating-sphere having a special ...
Indocyanine green loaded poly(lactic acid) nanoparticles mediated phototherapy of cancer

Güney, Melike. (Thesis (Ph.D.)-Bogazici University. Institute of Biomedical Engineering, 2022., 2022.)

Phototherapy is a promising approach for cancer treatment which can be uti lized alone or in combination with other treatment modalities. Among the available photosensitizers for phototherapy, indocyanine green (ICG) merits ...
Laser biostimulation and monitorization of wound healing by means of bioimpedance measurements

Solmaz, Hakan. (Thesis (Ph.D.)-Bogazici University. Institute of Biomedical Engineering, 2016., 2016.)

Wound healing is critically important for the quality of life. Substantial number of patients suffering from non-healing chronic wounds and having serious difficulties in their daily life are reported in wound healing ...
Laser brain surgery with near infrared lasers : investigation of the optimal parameters by real - time temperature monitoring

Tunç, Burcu. (Thesis (Ph.D.)-Bogazici University. Institute of Biomedical Engineering, 2016., 2016.)

The thermal damage of the surrounding tissue can be an unwanted result of continuous-wave laser irradiation. In order to propose an effective way alternative to conventional surgical techniques, photothermal damage must ...
Laser sterilization technique for root canal treatment: Investigating the use of thulium fiber laser

Kabaş Sarp, Ayşe Sena. (Thesis (Ph.D.)-Bogazici University. Institute of Biomedical Engineering, 2018., 2018.)

Conventional endodontic treatment uses a chemomechanical protocol to eliminate all infected debris and take the bacteria out from the root canal in order to prevent the development of persisting apical periodontal inflamation. ...
Photobiomodulation on human osteoblasts and osteogenic differentiation of adipose-derived stem cells

Bölükbaşı, Gamze. (Thesis (Ph.D.)-Bogazici University. Institute of Biomedical Engineering, 2017., 2017.)

The present in vitro comparative study evaluated parameters of osteogenesis under the inﬂuence of photobiomodulation (PBM). PBM uses light in the visible and near-infrared spectrum to induce a non-thermal process and to ...
Photodynamic therapy with upconversion nanoparticles

Güleryüz, Burcu. (Thesis (Ph.D.)-Bogazici University. Institute of Biomedical Engineering, 2022., 2022.)

Photodynamic therapy (PDT) is an alternative approach to conventional meth ods (i e. chemotherapy and radiotherapy) that can be utilized to treat various cancers with less side effects. However, PDT has some restrictions ...
Photofrin and indocyanine green-mediated photodynamic therapy in cancer treatment

Bozkulak, Özgüncem. (Thesis (Ph.D.)-Bogazici University. Institute of Biomedical Engineering, 2010., 2010.)

Photodynamic therapy (PDT) is a minimally invasive therapeutic approach for clinical treatment of cancer. PDT-mediated oxidative stress leads to cell death and can elicit the expression of genes associated with cell survival, ...
Skin tissue welding with near infrared lasers: investigation of the optimal parameters

Tabakoğlu, Haşim Özgür. (Thesis (Ph.D.)-Bogazici University. Institute of Biomedical Engineering, 2010., 2010.)

Laser tissue welding/soldering is an alternative to conventional closure techniques in surgery. In the present study, the closure capability and the contribution to recovery period of laser welding techniques were investigated ...
Strategies to increase photodynamic theraph efficacy on conventional and complex in vitro cancer models

Ruhi, Mustafa Kemal. (Thesis (Ph.D.)-Bogazici University. Institute of Biomedical Engineering, 2019., 2019.)

Cancer is one of the leading causes of death worldwide. Due to the side-eﬀects and ineﬃcacy of the conventional cancer treatment methods, alternative modalities are researched. Oneofthealternatives, PhotodynamicTherapy(P ...
