For the first time, we show mathematically that entangled states of class of vector beams are Majorana–like. Experimentally, enhanced transmission is observed in mouse brain from Majorana–like vector photons with orbital angular momentum.

Majorana like photons are introduced from class of classically entangled Cylindrical Vector Vortex Beams. An enhanced transmission is observed in mouse brain from Majorana vector photons with orbital angular momentum due to their non-separability.

Light transmission of Laguerre-Gaussian (LG) vortex beams in different local regions in mouse brain tissue is investigated. Transmittance is measured in ballistic region with various polarizations states and orbital angular momentums (OAM).

Brain samples from Alzheimer's patients and aged-matched controls were studied using label-free fluorescence. Increased tryptophan metabolite to tryptophan ratios were seen in the hippocampus and Brodmann's area 9 in Alzheimer's patients as compared to normal.

VRR spectroscopy was used for BCC and normal skin tissues with 532nm excitation. The spectra showed significant changes in collagen, carotenoids and lipids. These enhanced fingerprints demonstrate a potential use as label-free pathology method.

Resonance Raman spectroscopy using 532nm excitation was used to distinguish normal brain tissue from different grades of glioma tissues. Principal component analysis was used to analyze the spectral data and achieved high accuracy.

We characterize the entanglement after one of two polarization-entangled photons travels through a water-based soft-matter scattering medium: brain tissue. We consider tissue samples of distinct characteristics: thickness, water content, type, treatment and healthy or affected by disease.

A supercontinuum (SC) light microscope is proposed for linear and nonlinear optical resonance and non-resonance processes in medical and biological applications. The SC can span from 300nm to 2500nm and may be used for a variety of applications for diagnosis of cancer, wound healing, fusing tissues, stimulation of nerves for therapeutic and treatment of disease. These will be discussed.

New photovoltaic solar cells based on micro/meso porous Zinc(hydr)oxide with 2% graphite oxide (ZnGO-2) and TiO2 s sensitized by quantum dot and ICG dye are reported. The efficiency of energy conversion has reached up to ~ 6.84%.

The two-photon excitation and rapid relaxation of S2 state to S1 state makes wavelengths of excitation and emission fall in the “tissue optical window”, which can be used for deeper tissue imaging for two-photon microscope.
