Label-free imaging of thick tissue at 1550nm using a femtosecond optical parametric generator [PDF]
, 2015 We have developed a simple wavelength tunable optical parametric generator (OPG), emitting broad band ultrashort pulses with peak wavelengths at 1530-1790 nm, for nonlinear label-free microscopy.

Highly Sensitive Intravascular Photoacoustic Imaging with a Collinear Catheter Probe [PDF]
, 2016 A collinear catheter for label-free intravascular photoacoustic imaging was developed with a diameter of 1.6 mm. The collinear overlap between optical and acoustic waves enabled photoacoustic imaging of a human coronary artery from lumen to perivascular ...

Label-free optical imaging of membrane potential
Current Opinion in Biomedical Engineering, 2019 Offering high temporal resolution, voltage imaging is an important and essential technique in neuroscience. Among different optical imaging approaches, the label-free approach remains attractive due to its unique value coming from free of exogenous chromophores.

Label-free imaging of gelatin-containing hydrogel scaffolds [PDF]
Biomaterials, 2015 Composite hyaluronic acid (HA) hydrogels containing gelatin are used in regenerative medicine as tissue-mimicking scaffolds for improving stem cell survival. Once implanted, it is assumed that these biomaterials disintegrate over time, but at present there is no non-invasive imaging technique available with which such degradation can be directly ...

Fast label-free multilayered histology-like imaging of human breast cancer by photoacoustic microscopy [PDF]
, 2017 The goal of breast-conserving surgery is to completely remove all of the cancer. Currently, no intraoperative tools can microscopically analyze the entire lumpectomy specimen, which results in 20 to 60% of patients undergoing second surgeries to achieve ...

Label-Free Molecular Imaging of Living Cells
Molecules and Cells, 2008 Optical signals based on Raman scattering, coherent anti-Stokes Raman scattering (CARS), and harmonic generation can be used to image biological molecules in living cells without labeling. Both Raman scattering and CARS signals can be used to detect frequencies of molecular vibrations and to obtain the molecular distributions in samples.

Surface-enhanced Raman imaging of cell membrane by a highly homogeneous and isotropic silver nanostructure [PDF]
, 2015 Label-free, surface-enhanced Raman spectroscopic imaging of the challenging red blood cell membrane is achieved by using a near-hyperuniform disordered plasmonic nanostructure of silver nanoparticles.

Label-free molecular imaging of the kidney
Kidney International, 2017 In this review, we will highlight technologies that enable scientists to study the molecular characteristics of tissues and/or cells without the need for antibodies or other labeling techniques. Specifically, we will focus on matrix-assisted laser desorption/ionization imaging mass spectrometry, infrared spectroscopy, and Raman spectroscopy.
