2011 Yale Microscopy Workshop

Dear Colleagues,

We invite you to participate in a three day workshop. This free  annual event is a combination of symposium, practical classes and open access to a wide variety of microscopes. This year's symposium is focused on Super-Resolution Microscopy. It is open to the international research community and only requires registration.
Please visit the website for a complete schedule and list of equipment <http://microscopy.med.yale.edu>http://microscopy.med.yale.edu

Name: 2011 Yale Microscopy Workshop
Time: June 7 - 9th, 2011
Location: Yale Medical School, The Anlyan Center (TAC), New Haven, CT
Cost: Free on-line and on-site registration
Information: <http://microscopy.med.yale.edu/index.html>http://microscopy.med.yale.edu/index.html

Features:
- symposium on Super-Resolution Imaging
- walk-in clinics, demonstrations and open access to fully functional
microscopes
- multi vendor participation (over 8 vendors)
- a practical "micro-course" will be offered on photoconversion

In addition to a large variety of confocals, spinning disks, and widefields provided by over 8 vendors, multiple super-resolution microscopes will be available for use throughout the workshop.
Several microscopes will have their first open-access debut at this event:
- Nikon N-STORM microscope
- Leica ground state depletion for super-resolution
- Vutara SR-200 3D multi-channel super-resolution microscope

Reservations can be made for many of the instruments after registration. View this as an opportunity to perform a "surgical strike" exploration of new instrumentation or techniques without any financial or time commitments. Feel free to come for advice from vendor representatives or to try out a microscope even if you are not attending a class or a seminar.

Please see the website for free registration, a schedule of events, and list of equipment. <http://microscopy.med.yale.edu/index.html>http://microscopy.med.yale.edu/index.html

Please feel free to disseminate information about this workshop by word-of-mouth or through email at your institution. Need to try out an instrument that is not on the list but manufactured by a vendor that is already participating? Write to an organizer and we'll see if they can bring it.

We look forward to seeing you there - please reserve early.

The organizers,

Nanodiamond Drug Device Could Transform Cancer Treatment

... in their study, Ho and his colleagues embedded millions of tiny drug-carrying nanodiamonds in the FDA-approved polymer parylene. Currently used as a coating for implants, the biostable parylene is a flexible and versatile material resembling plastic wrap. A substantial amount of drug can be loaded onto clusters of nanodiamonds, which have a high surface area. The nanodiamonds then are put between extremely thin films of parylene, resulting in a device that is minimally invasive...

Nanodiamond conjugate induces cancer cell death and inhibits tumorigenesis

Researchers in Taiwan have manipulated nanodiamond (ND), a carbon nanomaterial, to covalently link paclitaxel for cancer drug delivery and therapy. Paclitaxel was bound to the surface of 3–5 nm sized ND through a succession of chemical modifications. The ND-paclitaxel conjugation was measured by atomic force microscopy and nuclear magnetic resonance spectroscopy, and confirmed with infrared spectroscopy by the detection of deuterated paclitaxel.

Schematic setup of Trestles LH10-fs/CW laser system with built-in pump laser

Del Mar Photonics supply Trestles lasers as stand alone system, or as a one-box system with built-in DPSS pump laser.
The price of the system with DPSS pump depends on required output power.

The standard tuning elements indicated below are used in CW Ti:Sapphire lasers such as Trestles CW or Trestles fs/CW.

Those elements are also sold separately as standrad items or as a custom made components.

1) Thick etalon - request a quote
Thickness - 3 mm, diameter - 20 mm. Surface quality: Ð=1-2, N<1, ΔN<0.1,
λ/10, plane parallelism better than 10''. Thickness accuracy 5 um.

2) Thin etalon - request a quote
Thickness - 200 um, diameter - 15 mm. Surface quality: Ð=1-2, N<1, ΔN<0.1,
λ/10, plane parallelism better than 10''. Thickness accuracy 5 um.

3) Birefringent filter BRF - request a quote

We use a 3-plate assembled BRF (Lyot filter) with adjustable motorized mount (see attached drawing).

Total losses introduced into the cavity by the filter are 5% of the laser’s output power. The FSR is defined by the thinnest plate and equals to around - 1.3*10¹⁴ Hz, while the maximum width is controlled by the thickest plate and equals to approx. 3.1*10¹² Hz.

Dimensions of plate assembly ('filter' in the picture): dia 44.5 mm, t=13.5 mm. It should be properly aligned (Brewster to the beam) and rotated by some rotating mount around its axis to provide wavelength tuning.
