Biomedical Applications of Photochemistry

Abstract

Photochemistry is the study of photochemical reactions between light and molecules. Recently, there have been increasing interests in using photochemical reactions in the fields of biomaterials and tissue engineering. This work revisits the components and mechanisms of photochemistry and reviews biomedical applications of photochemistry in various disciplines, including oncology, molecular biology, and biosurgery, with particular emphasis on tissue engineering. Finally, potential toxicities and research opportunities in this field are discussed.

Study of Formation and Decay of Rare-Gas Excimers by Laser- Induced Fluorescence

“…Vacuum ultraviolet (VUV) radiation sources are of great interest for many applications such as photochemistry, surface treatment, sterilization, water treatment, photolithography and mercury-free lamps [1][2][3][4]. These applications often use dielectric barrier excimer lamps [5][6][7][8][9][10][11].…”

Fiber Optical Tweezers for Applying and Measuring Forces in a 3D Solid Compartment

“…For example, under laser illumination, local temperature changes originating from optical absorption of the trapped particle can change the surrounding medium viscosity [30]. The polyacrylamide gel stiffness has also been observed to change under localized laser illumination [31,32]. Moreover, polyacrylamide gel mechanical integrity can also be changed [31] due to the nature of polyacrylamide gel swelling.…”

“…The polyacrylamide gel stiffness has also been observed to change under localized laser illumination [31,32]. Moreover, polyacrylamide gel mechanical integrity can also be changed [31] due to the nature of polyacrylamide gel swelling. In addition, the effective polyacrylamide gel property may be influenced due to the imperfect contact condition at the interface between bead and surrounding polyacrylamide gel.…”

Structural and optical studies on selected web spinning spider silks

“…The high production rate should be possible by enhance the mechanical property of spider silk. The method of UV crosslinking is also wellknown in biomedical engineering for enhancing the mechanical properties of biomaterials [14]. In effect of exposing UV radiation on spider silks, the electrons in the material excited and will alter the kinetics of chemical reactions and it promotes the process of enhanced mechanical property [15,16].…”
