Near-infrared squaraine dye encapsulated micelles for in vivo fluorescence and photoacoustic bimodal imaging
Combined near-infrared (NIR) fluorescence and photoacoustic imaging techniques present promising capabilities for noninvasive visualization of biological structures. Development of bimodal noninvasive optical imaging ...
Real time monitoring of aminothiol level in blood using a near-infrared dye assisted deep tissue fluorescence and photoacoustic bimodal imaging
The development of molecular probes for the detection and imaging of biological thiols is a major step forward diagnosing various types of diseases. Previously reported thiol imaging strategies were mainly based on a single ...
A ratiometric fluorescent molecular probe with enhanced two-photon response upon Zn 2+ binding for in vitro and in vivo bioimaging
A bipyridine centered donor–acceptor–donor (D–π–A–π–D) type ratiometric fluorescent molecular probe exhibited an unprecedented enhancement in the two-photon absorption (2PA) cross section upon Zn2+ binding. Moreover, owing ...
Superior optical nonlinearity of an exceptional fluorescent stilbene dye
Strong multiphoton absorption and harmonic generation in organic fluorescent chromophores are, respectively, significant in many fields of research. However, most of fluorescent chromophores fall short of the full potential ...
Poly(acrylic acid)-capped and dye-loaded graphene oxide-mesoporous silica : a nano-sandwich for two-photon and photoacoustic dual-mode imaging
Growth of mesoporous silica on both sides of graphene oxide affords a nano-sandwich (NS) material. A two-photon active dye is then loaded into the mesopores of the NS followed by sealing with poly(acrylic acid). The obtained ...
Morphology-tuned exceptional catalytic activity of porous-polymer-supported Mn3O4 in aerobic sp3 C-H bond oxidation of aromatic hydrocarbons and alcohols
Mn3O4 nanomaterials with different morphologies (sphere, nanowire, and octahedron) embedded into functionalized nanoporous polymers were developed by a facile one-pot solvothermal technique at different temperatures. These ...
