An imaging agent for detecting analytes in a biological environment includes functionalized, silicon vacancy center-containing nanodiamonds. Individual nanodiamonds of the imaging agent include at least one silicon vacancy center. The at least one silicon vacancy center can emit light having a wavelength in a narrow band in response to illumination having any wavelength in a wide range of wavelengths. The nanodiamonds are functionalized to selectively interact with an analyte of interest. The nanodiamonds can additionally include other color centers, and the imaging agent can include a plurality of sets of nanodiamonds having detectably unique ratios of silicon vacancy centers to other color centers. The silicon vacancy centers in the nanodiamonds can have a preferred orientation enabling orientation tracking of individual nanodiamonds or other applications. A method for detecting properties of the analyte of interest by interacting with the imaging agent is also provided.

Tracer materials that are identifiable in a fluid using electromagnetic signals are integrated into a host material that can be machined into a tool for use in a wellbore. The host material can be dissolvable and designed to dissolve at a certain rate and under certain environmental conditions in the wellbore. As the host material dissolves the tracer material is released into the wellbore where it is measured. Methods of integrating the tracer material and host dissolvable material together are also disclosed.

Systems and methods of electrostatically spraying a treatment solution are disclosed that include electrostatically charging, by a cartridge assembled with a handheld portable electrostatic device, a treatment solution. The handheld portable electrostatic device can include a housing, the cartridge removably disposed in the housing. The cartridge can include a cartridge housing, at least one electrode to electrostatically charge and ionize molecules of the treatment solution of the cartridge, and a nozzle positioned at a distal end of the cartridge housing, the nozzle of the cartridge being configured to deliver the electrostatically charged treatment solution and configured to be in fluid communication with an air supply tube in fluid communication with a pump in the housing.

Described is a testing assembly and method for testing performance of a tracer. The testing assembly includes a sample housing containing a tracer sample in fluid connection with a mass flow controller. The mass flow controller is connected with a source of an inert gas and controls a rate of flow of the inert gas into the sample housing. An injection device is connected with the sample housing to introduce a treatment fluid into the sample housing. A differential pressure transducer measures a change in pressure within the sample housing. A filtering device in connection with the sample housing filters a resultant fluid to capture tracer particulate matter that is released from the sample housing. The tracer particulate matter and resultant fluid are analyzed for presence of the tracer at various time points in order to evaluate degradation of the tracer under simulated gas reservoir conditions.

The present disclosure encompasses apparatuses, methods and systems for monitoring, predicting, replicating and simulating particle ray tracing and interfacing said tracing with alert, response, measurement and entertainment systems or devices in an ergonomic fashion. Among the objectives of this disclosure is to provide related variations to designs that protect, guide, inform, or entertain users or systems. In order to accomplish this feat, the disclosure requires one or more particle ray observation sensors (PROS), which observe particles and their movement and send a signal to one or more particle ray response relays (PRRR), which perform an action in response to a said signal. Developments from this disclosure can be used to build safety devices that assist users, protect users from danger, assist dental hygiene, duplicate live music in other real or virtual environments, and help commercial assessors value buildings, renovations or optimal use of space with the aid of Artificial Intelligence.
