What is the role of melanin in UV absorption in films?
Best insight from top research papers
Melanin plays a crucial role in UV absorption in films. It has the ability to dissipate UV energy and serve as a natural photo-protectant . Melanin films produced by oxidation of dopamine have been found to absorb strongly over the entire UV/Vis part of the electromagnetic spectrum . These films are impermeable to anions, even at low film thickness . The addition of melanin to film-forming materials can improve the UV shielding properties of the film . Melanin nanoparticles have excellent photothermal conversion and UV-proof performance, which enhances the heat preservation effect of the film . Synthetic melanin films deposited using matrix assisted pulsed laser evaporation (MAPLE) preserve the optical properties and molecular structure typical of melanins, allowing for UV absorption .

What is the effect of radiation UV on melanogenesis?5 answersUV radiation has been found to have various effects on melanogenesis. Low-dose UVB radiation increases global m6 A modification in melanocytes, which promotes melanogenesis. UV radiation activates the cAMP-mediated PKA/CREB/MITF pathway, which is the main pathway for melanogenesis. UVA radiation induces oxidative stress, dysregulation of gene transcription, and creation of mutagenic photoproducts in DNA, negatively affecting melanocytes. Additionally, UVA exposure has been associated with an increased risk of melanoma, as shown in epidemiology studies. Furthermore, lamb placenta peptide powder has been found to inhibit melanin production, both in vitro and in vivo, suggesting its potential as a functional food material for melanogenesis inhibition.
What is melanin absorption at 1064nm?5 answersMelanin absorption at 1064nm is not explicitly mentioned in the abstracts provided. However, one paper discusses the absorption coefficients of melanin in the visible and near-infrared (NIR) range. The paper states that melanin is a better absorber of visible light than black polystyrene, and provides absorption coefficients for melanin in the NIR range, ranging from 3713 cm^-1 at 800nm to 222 cm^-1 at 1319nm.
What are roles of melanin in the human?2 answersMelanin plays several roles in the human body. One of its primary functions is to protect the skin from UV-induced DNA damage. Melanin is delivered to keratinocytes in the skin after being excreted as melanosomes from melanocytes. Melanin production defects can lead to diseases such as skin cancer, vitiligo, and albinism. Melanin-like nanoparticles have been synthesized and studied for their UV-protective capabilities in human keratinocytes. Melanocytes, which produce melanin, have been found to have innate immune activities and can respond to bacterial and viral infections. Melanocytes produce cytokines and chemokines that alert immune cells and contribute to the immune and inflammatory responses in the skin. Melanin in melanocytes can also regulate oxidative stress, and its presence in the skin protects melanocytes and neighboring keratinocytes from UV radiation but may increase melanoma susceptibility. Melanocytes have the capacity to synthesize and secrete signal molecules, suggesting their involvement in regulatory pathways beyond melanogenesis.
In which wavelength in UV-Vis absorb the AMINE groups?2 answersAmine groups absorb in the UV-Vis range, specifically in the wavelength range of 200 to 260 nm. The absorption spectrum of a monosubstituted polyacetylene with amine functional groups starts around 700 nm, which is due to the π→ π* interband transition of the conjugated polymer system.
