Gold Nanoparticles for Biology and Medicine [PDF]

open access: yesAngewandte Chemie - International Edition, 2010
AbstractGold colloids have fascinated scientists for over a century and are now heavily utilized in chemistry, biology, engineering, and medicine. Today these materials can be synthesized reproducibly, modified with seemingly limitless chemical functional groups, and, in certain cases, characterized with atomic‐level precision.

Effect of size, shape, and surface modification on cytotoxicity of gold nanoparticles to human Hep-2 and canine MDCK cells [PDF]

open access: yes, 2012
There have been increasing interests in applying gold nanoparticles in biological research, drug delivery, and therapy. As the interaction of gold nanoparticles with cells relies on properties of nanoparticles, the cytotoxicity is complex and still under

Fluorescent Radiosensitizing Gold Nanoparticles [PDF]

open access: yesInternational Journal of Molecular Sciences, 2019
Ultrasmall polyaminocarboxylate-coated gold nanoparticles (NPs), Au@DTDTPA and Au@TADOTAGA, that have been recently developed exhibit a promising potential for image-guided radiotherapy. In order to render the radiosensitizing effect of these gold nanoparticles even more efficient, the study of their localization in cells is required to better ...

Gold Nanoparticles in Cancer Theranostics [PDF]

open access: yesFrontiers in Bioengineering and Biotechnology, 2021
Conventional cancer treatments, such as surgical resection, radiotherapy, and chemotherapy, have achieved significant progress in cancer therapy. Nevertheless, some limitations (such as toxic side effects) are still existing for conventional therapies, which motivate efforts toward developing novel theranostic avenues.

Polyelectrolyte-modified cowpea mosaic virus for the synthesis of gold nanoparticles [PDF]

open access: yes, 2013
Polyelectrolyte surface-modified cowpea mosaic virus (CPMV) can be used for the templated synthesis of narrowly dispersed gold nanoparticles. Cationic polyelectrolyte, poly(allylamine) hydrochloride, is electrostatically bound to the external surface of ...

High Sensitivity DNA Detection Using Gold Nanoparticle Functionalised Polyaniline Nanofibres [PDF]

open access: yes, 2010
Polyaniline (PANI) nanofibres (PANI-NF) have been modified with chemically grown gold nanoparticles to give a nanocomposite material (PANI-NF–AuNP) and deposited on gold electrodes. Single stranded capture DNA was then bound to the gold nanoparticles and

Mixed metal nanoparticle assembly and the effect on surface enhanced raman scattering [PDF]

open access: yes, 2010
Here we report the assembly of mixed metal nanoparticles using an oligonucleotide-templated approach. Substitution of one of the gold nanoparticle probes with an analagous silver probe to produce a hetero-metal duplex permitted surface enhanced Raman ...

Bleaching of sol-gel glass film with embedded gold nanoparticles by thermal poling [PDF]

open access: yes, 2006
Gold clusters embedded in glass are expected to be hard to dissolve in the form of ions since gold is essentially a nonreactive metal. In spite of that, bleaching of Au-doped nanocomposite sol-gel glass film on a soda-lime glass substrate is demonstrated
