Described herein are devices, systems and methods for delivering therapeutic compositions to plants. Specifically exemplified herein is a device comprising a plurality of microneedles for creating pores in an effective area of a target plant and then applying a second device loaded with the therapeutic composition. The microneedle device is designed to impart pores that allow for access of the therapeutic composition to the plant vascular system including phloem.

Phloem-based delivery of therapeutics

A sensor device is for detecting metal. The sensor device may have a substrate, an electrode on the substrate, and a biopolymer-metal composite film on the electrode. The biopolymer-metal composite film may include a metal and a biopolymer. The sensor device may further have circuitry coupled to the electrode and configured to apply a sensing signal to the electrode.

Sensor device with biopolymer-metal composite film and related methods

A monochloramine microsensor includes an elongated housing defining a central axis and an open interior and having a capillary opening at one end. A semi-permeable membrane covers the capillary opening, the semi-permeable membrane allowing diffusion of chloramines there-through while preventing water from entering into the interior of the housing. A chloramine sensitive element in the form of a wire, fiber or nanotube is mounted within the housing, the chloramine sensitive element, when used in conjunction with an anode, outputs current in an amount proportional to the concentration of chloramine present in a liquid sample in which the chloramine sensitive element is immersed. The chloramine sensitive element extends along a length of the central axis to a first end adjacent to and spaced from the semi-permeable membrane. The chloramine sensitive element is a gold wire, a platinum wire, a carbon fiber or a carbon nanotube.
