Most commercial laser-scanning imaging systems used for confocal fluorescence microscopy can be readily adapted for use with two-photon fluorescence excitation. We report here on the details of the conversion of the Nikon C1 (product released November 2001) with two channels of nondescanned detection of two-photon-excited fluorescence. One of the goals of the design was to utilize off-the-shelf components as much as possible to minimize the use of custom machining and electronics assembly. We also give some initial characterization of the imaging properties of the system.

Implantable electronic devices such as pacemakers and neural implants are often used for electrical stimulation. The usage of microfabrication techniques to produce microelectromechanical systems (MEMS) has allowed engineers to address a wider range of clinical indications. A new direction in the area of MEMS technology is the goal of achieving pulsatile drug delivery. The digital capabilities of MEMS may allow greater temporal control over drug release compared to traditional polymer-based systems, while the batch-processing techniques used in the microelectronics industry can lead to greater device uniformity and reproducibility than is currently available to the pharmaceutical industry. A repertoire of structures, including microreservoirs, micropumps, valves, and sensors, is being developed that will provide a strong foundation for the design of integrated, responsive MEMS for drug delivery.
