Low Level Light Therapy: What Comes Next

Posted by Elieza Tang | Aug 22, 2014 5:30:34 PM

The agenda of this Low Level Light Incubator has taken a bottom up approach to light therapy. We began by establishing the foundation through explaining the basic mechanism and science of LLLT, then moving on to preclinical data and research and finally day two brought us to the application of LLLT in the clinical setting. Today the current use of LLLT for pain management, improving cognitive function in chronic traumatic brain injury and treatment of oral mucositis were addressed. In addition, a social and ethical session addressed the need to on develop a consensus on professional commitments for a new collaborative initiative in health care in order to bring LLLT to the forefront of clinical care.

Low-Level Light in the Clinical Setting

Posted by Elieza Tang | Aug 22, 2014 10:19:00 AM

As the Low-Level Light Incubator continued, the focus turned to pre-clinical and laboratory studies that demonstrate the biostimulatory effects of photobiomodulation (PBM) and the possibility of LLLT to be used as a standard treatment modality in the clinical setting.

Low Level Light Therapy: the Path Forward

Posted by Elieza Tang | Aug 21, 2014 5:36:00 PM

OSA’s 15th Incubator, focusing on Low Level Light Therapy (LLLT) also known as photobiomodulation (PBM) is up and running. LLLT/PBM describes the use of light therapy in the visible and near-infrared spectrum for stimulating biological responses. Extensive laboratory experiments and clinical trials have demonstrated PBM to be efficacious in tissue regeneration including the skin, muscle, nerves, bone, spinal PBM has been shown to produce an analgesic effect, anti-inflammatory effect and promote angiogenesis. The results from these controlled clinical trials and laboratory studies provides exciting and convincing evidence for the use of PBM as an efficacious, noninvasive treatment modality in the clinical setting. Many of these studies have demonstrated improved results and recovery with conditions such as traumatic brain injury, chronic wounds, spinal cord injury and many other injury models.

However, PBM has yet to be adopted by mainstream medicine. Why you ask? There are different answers based on who you ask.

The OSA Photovoltaics Meeting - Optics and Energy Needs

Posted by Baohua Jia | Aug 13, 2014 5:32:00 PM

I have worked at Swinburne University of Technolgy in Australia as a senior scientist in the field of nanophotoncs solar cell since 2010. For people who are not familar with this field, basically we design nanostructures and nanomaterials to allow more light going into solar cells and help the light to be trapped inside the cells. This way, more electricity can be harvested from solar cells. 

Some estimate that we'll deplete our fossil fuel in 60-70 years. Sounds like a long time - but it's not. The matter is urgent right now.

Optics plays a critical role in securing the global energy future, and I believe solar energy is the best hope to meet future energy challenges. We have enough. It's clean. Everyone can enjoy it without extra effort. But it is not cheap. However, with the joint efforts from experts in optics and PV, this problem might be tackled soon.

Awesome Optics at AIO

Posted by Arlene Smith | Jul 24, 2014 10:39:00 AM

The morning session of Day 4 - Awesome Optical Materials - was opened by Dr. Tigran Galstian (Universite Laval & LensVector). Tigran presented a liquid crystal-based motion-less adaptive optical system. This cost-effective approach has been successfully applied to mobile phone camera technology to enable autofocus, with future applications in LED lighting and ophthalmic products (contact lenses and intraocular lenses). Dr. Alexandre Brolo (University of Victoria) spoke about tailoring metallic nanostructures for Surface-Enhanced Raman Spectroscopy (SERS). Alexandre also discussed various potential applications for SERS probes, such as in designing customized cancer treatment by imaging the protein expression in dysplastic cells.
